%\begin{abstract}
% This class is designed to typeset laboratory journals with \LaTeX\
% that contain chronologically ordered records about experiments. Each
% day, the new pages are simply added at the end, and from the
% sectioning commands, an experiment index is generated to make it
% easier to find a particular experiment. Because |\frontmatter| has
% roman page numbering, it is easy to separately extend index, toc and
% list of abbreviations. The class is based on the KOMA-Script class
% |scrbook.cls|. Therefore all features of this class can be used --
% reading of |scrguide| (german) or |scrguien| (english), the
% documentation of KOMA-Script, is highly recommended.

% \section{General information}
%
%
% \subsection{Legal considerations}
%
% Writing of laboratory journals is sometimes regulated by law,
% often funding institutions have additional requirements. Thus it is
% usually \emph{not} allowed to keep a lab journal in electronic form
% only; sometimes even hardcover books have to be used. On the other
% hand it seems to be common practice to keep notes on loose leafes,
% computer files or a jotter book and compile them in the hardcover
% lab journal in a more or less regular manner.
%
% Therefore it seems tenable to work with an electronic version of the
% journal and a printout in parallel. If required, the printout can be
% clipped or bound, and a version on a CD-ROM should have equal
% value as evidence as a book. On the other hand, one gains a lot,
% especially with a PDF version: full text search, easy inclusion of
% graphs and pictures, possibility of hyperlinking to data files etc.
%
% \subsection{Features}
% \label{sec:features}
%
% \begin{description}
% \item[basis class] |labbook.cls| is based on the KOMA-Script-class
% |scrbook.cls|. Therefore it offers all the features of this class:
% changing the page layout, head- and footlines, paragraph markup, and
% changing appearance of floats and margin notes. It is highly
% recommended to read the documentation, scrguien.
% \item[Sectioning] The lab journal is structured in a chronological
% way. Instead of |\chapter|, |\labday| is used. Within a day the
% text is sectioned according to experiments -- this can be a
% complete measurement from design to evaluation, but also one test
% in a series that takes several days. |\experiment| is on the level
% of section, and there is |\subexperiment| which corresponds to
% |\subsection|. Below that, the usual sectioning commands can be
% used (although their usage doesn't seem very sensible to me,
% mind KOMA-script's |\minisec| command).
% \item[Index and table of contents] Because of the chronological
% structure, a traditional table of contents is not sufficient,
% especially if investigations in a series of experiments are
% conducted on different days. Therefore, an index is created. It is
% built from the toc entries of the sectioning commands. One can
% also define abbreviations to use in the argument of |\experiment|
% and |\subexperiment|. Thus, the consistent creation of the index
% is much easier. Furthermore, you can create multiple index
% entries for one experiment.
% \item[hyperref integration] The class works together well with
% |hyperref.sty| to produce PDF files with navigation features.
% \end{description}
%
% \section{Usage}
% \label{sec:usage}
%
%
% \subsection{Initialization}
% \label{sec:options}
%
% If you want to use hyperref.sty, you \emph{must} specify the class
% option |hyperref| like this
% \begin{verbatim}\documentclass[hyperref]{labbook}\end{verbatim}
% after that you can load hyperref and other packages
% in the order appropriate for your document. If you load hyperref.sty
% without giving the option, hyperref will overwrite some changes this
% class makes to \LaTeX\ internals. If you use hyperref, you should
% also consider the KOMA option |idxtotoc|: The index will not only be
% listed in the table of contents, but also in the PDF bookmarks.
%
% Besides that, all options you specifiy are just handed on to
% |scrbook.cls|. You might want to use |openany| to allow new labdays
% to begin on any page.
%
% \section{Sectioning commands}
% \label{sec:gliederungsbefehle}
%
%\subsection{\textbackslash\texttt{labday}}
%\label{sec:labday}
%
% \DescribeMacro{\labday}
% |labday| can be used to create an unnumbered heading formatted like a
% chapter. Its text is put into the table of contents and used as
% running title -- usually one would just use the date, perhaps with the
% weekday. It should be used only within mainmatter and will take care
% of index entries for the lower sectioning levels (see below). It calls
% |\addchap| internally, there is no starred form or optional argument
% to |\labday|.
%
% \subsection{\textbackslash\texttt{experiment} and
% \textbackslash\texttt{subexperiment}: The simple usage}
% \label{sec:exper-und-subexp}
%
% \DescribeMacro{\experiment}
% Within a |\labday|, numbered headlines for
% single experiments can be created with
% \begin{verbatim}\experiment[]{long form}\end{verbatim}
% Its text (or that of the optional argument) is not only typeset in the
% table of contents and page head, but also in the index. This eases the
% orientation, particularly if experiments are done several times or
% take longer than one day. The index entries specify the page range of
% the whole experiment, not only the starting page; and if the same
% experiment is repeated on different days that fall on subsequent
% pages, one common index range is generated.
%
% Note that you cannot use commas\footnote{In fact, the string
% \texttt{\MVAt--\MVAt} is not allowed, too -- see the implementation
% notes below.} in the optional argument (see below). If you
% have to, enclose the optional argument in additional curly braces:
% \begin{verbatim}
% \experiment[{one, two, three}]{The one, the two and the three}
% \end{verbatim}
%
% \DescribeMacro{\subexperiment} Below |\experiment| you can use
% |\subexperiment| which works in the same way and produces
% sub-indexentries. It is intended for sections like ``design,
% realization, evaluation'' or ``preparation, purification,
% measurement''.
%
%
% \subsection{Advanced Usage: Experiment Abbreviations}
% \label{sec:abkurzungen}
%
% \DescribeMacro{\newexperiment}
% If one uses slightly different wording (or spelling) in two occurences
% of the same experiment, they will get different index entries. To
% avoid this, one can define abbreviations for frequently used
% experiment headlines, toc and index entries. This is done with the macro
%
% |\newexperiment{}[]{}|
%
% Here, || is the abbreviation that can be given later to make
% \LaTeX\ use the || and ||. The short form is
% for index, table of contents and running title, and giving it is
% optional. When using the abbreviation, specify it \emph{without}
% prepending a backslash, i.e. |\experiment{abbrev}|. Abbreviations may
% contain any char except the backslash, the tilde (\textasciitilde),
% commas and spaces.
%
% \DescribeMacro{\newsubexperiment}
% For |\subexperiment|, there is an analogous macro,
% |\newsubexperiment|.
%
% If you try to define an abbreviation that has already been used, you
% will get an error message. You can use the same abbreviation for one
% experiment and one subexperiment entry (although doing this may cause
% confusion, not to TeX, but to you). If you leave out the optional
% argument, the long form is also used for index and table of contents.
%
% Usually you just type |\experiment{abbrev}|, but you can also combine
% a varied text in the long form with an abbreviation in the optional
% argument: |\experiment[abbrev]{varied text}|, to make sure the index
% stays simple. You cannot use a free text optional argument with an
% abbreviation in the mandatory argument (because the abbreviation yet
% has an associated index entry). But it is, in principle, possible to
% use two different abbreviations in optional and mandatory argument -
% but only as long as both yield the same index entry.
%
%
% \subsection{Fancy stuff: Multiple index entries for experiments}
% \label{sec:mult-index-entr}
%
% Sometimes one performs corresponding working steps of different
% experiments in parallel -- this complicates index entries. Consider
% that by some screening method you have identified the substances A152
% and B96 from a combinatorial library as promising drugs
% against some disease. The next things to do is to verify their exact
% structure, composition or sequence and establish a medium-scale
% preparation protocol for further characterization. Probably you can
% save time by doing some of these steps in parallel, but you will end
% up with index entries like ``A152 and B96, sequencing'' -- and two
% months later you will have to remember wether you sequenced B96
% together with A152 or rather, the following week, with A43 and
% C12. Therefore it would be nice to get two index entries for the
% experiment ``Sequencing of A152 and B96'', namely ``A152, sequencing''
% and ``B96, sequencing''. And you can have exactly that.
%
% \DescribeMacro{\experiment}\DescribeMacro{\subexperiment}
% In fact the syntax for both |\experiment| and |\subexperiment| allows
% for a comma separated list in the optional argument. The first element
% will be used for table of contents and page head, and the following
% elements will produce index entries. Suppose you have defined the
% abbreviations A152-seq and \mbox{B96-seq}, you can thus say:
% \begin{verbatim}
% \experiment[Sequencing of A152 and B96, A152-seq, B96-seq]{Sequencing
% of inhibitor candidates A152 and B96}
% \end{verbatim}%
% and get what you want. Spaces before and after the commas will be
% ignored. You're free to use abbreviations or free text anywhere, but
% for the index entries only abbreviations really make sense.

%
% \subsection{Options}
%
% Some packages the user might use have to be loaded before hyperref, so
% this class cannot load it internally. However, we have to take care of
% it because of two reasons: One is that we need to provide it with some
% macros for our new sectioning levels, the more important is that we cannot
% redefine |\addcontentsline| before hyperref has done it. But we can't
% simply delay this until after hyperref has been loaded, since this
% might never occur.
%
% \changes{v1.1}{2003/05/20}{removed hardwired KOMA option openany}

% \end{macrocode}
%
% \section{Experiment abbreviations}
% \label{sec:experiment-abbr}
%
% To facilitate the creation of the index (specifically to avoid that
% little differences or typos mess it up), the user may define
% abbreviations for his experiment (and subexperiment) headings. This
% can be done using the macro |\newexperiment|. It's first argument is
% the abbreviation, then comes an optional short form for index
% entries, table of contents and running titles. Last comes the
% mandatory title argument.
%
% Then we check wether |\newexperiment| has been called with an optional
% argument, and call the respective commands. |\@ifnextchar| looks for
% the first character after the first argument, and keeps it. Thus, the
% following macros get the same arguments that |\newexperiment| had.
%
% \begin{macrocode}
\def\newexperiment#1{%
\@ifnextchar [{\opt@arg@newexperiment{#1}}%
{\nopt@arg@newexperiment{#1}}%]
}
% \end{macrocode}
%
% The long and short forms for \textit{\texttt{abbrev}} are assigned to
% |\long@|\textit{\texttt{}} and
% |\short@|\texttt{\textit{}}, respectively. After checking wether
% \textit{\texttt{abbrev}} has not yet been used, the second argument is assigned
% to the long and short form for the case when there was no optional
% argument. In case of an optional argument, this is used for the
% short form.
%
% \begin{macrocode}
\def\nopt@arg@newexperiment#1#2{%
\@ifundefined{long@exp@#1}{%
\@namedef{long@exp@#1}{#2}%
\@namedef{short@exp@#1}{#2}%
}{%
\ClassError
{labbook}
{experiment abbreviation yet defined}
{The abbreviation for an experiment that you wanted to define
with this command has already been defined.}%
}
}
\def\opt@arg@newexperiment#1[#2]#3{%
\@ifundefined{long@exp@#1}{%
\@namedef{long@exp@#1}{#3}%
\@namedef{short@exp@#1}{#2}%
}{%
\ClassError
{labbook}
{experiment abbreviation yet defined}
{The abbreviation for an experiment that you wanted to define
with this command has already been defined.}%
}
}
% \end{macrocode}
%
% The same is done for |\subexperiment|. Any subexperiment abbreviation
% may be used within any experiment.
%
% \begin{macrocode}
\def\newsubexperiment#1{%
\@ifnextchar [{\opt@arg@newsubexperiment{#1}}%]
{\nopt@arg@newsubexperiment{#1}}%
}%
\def\nopt@arg@newsubexperiment#1#2{%
\@ifundefined{long@subexp@#1}{%
\@namedef{long@subexp@#1}{#2}%
\@namedef{short@subexp@#1}{#2}%
}{%
\ClassError
{labbook}
{experiment abbreviation yet defined}
{The abbreviation for an experiment that you wanted to define
with this command has already been defined.}%
}%
}%
\def\opt@arg@newsubexperiment#1[#2]#3{%
\@ifundefined{long@subexp@#1}{%
\@namedef{long@subexp@#1}{#3}%
\@namedef{short@subexp@#1}{#2}%
}{%
\ClassError
{labbook}
{experiment abbreviation yet defined}
{The abbreviation for an experiment that you wanted to define
with this command has already been defined.}%
}%
}%
% \end{macrocode}
%
% Note that the usage is |\experiment{|\textit{\texttt{abbrev}}|}|,
% \emph{not} |\experiment{\|\textit{\texttt{abbrev}}|}|
%
% \section{Defining internal macros}
% \label{sec:defin-intern-macr}
%
% We first define some internal helper macros that we will use for
% different purposes.
%
% \subsection{Macros for argument parsing}
% \label{sec:macr-argum-pars}
%
% \subsubsection{Parsing a comma separated list}
% \label{sec:pars-comma-separ}
%
% The new sectioning commands can be used with a comma separated list of
% items in the optional argument (see below, \ref{sec:optarg-exp}), and
% we will be constructing a similar list if there is one more index entry
% for one sectioning command. To parse this list, we use code that is
% essentially taken from |keyval.sty| (page 4 in its manual).
%
% First we need some helper macros. |\FK@@sp@def| defines the control
% sequence in its first argument to expand to its second argument, but
% with any leading or trailing whitespace removed.
%
% \begin{macrocode}
\def\@tmpA#1{%
\def\FK@@sp@def##1##2{%
\futurelet\FK@tempa\FK@@sp@d##2\@nil\@nil#1\@nil\relax##1}%
\def\FK@@sp@d{%
\ifx\FK@tempa\@sptoken
\expandafter\FK@@sp@b
\else
\expandafter\FK@@sp@b\expandafter#1%
\fi}%
\def\FK@@sp@b#1##1 \@nil{\FK@@sp@c##1}%
}%
\def\FK@@sp@c#1\@nil#2\relax#3{\FK@toks@{#1}\edef#3{\the\FK@toks@}}%
\newtoks\FK@toks@%
\@tmpA{ }%
% \end{macrocode}
%
% Now we define a way to parse the optional argument and break it at
% every comma. |\fk@getcommasep@list| is a wrapper macro. It executes
% its first argument once before the list is read, assigns its further
% arguments to actions that will be done while going through the list,
% and then calls |\fk@@getcommasep@list| which takes as its argument the
% first element of the list after it, i.e. everything up to the first
% comma. It then works through the previously defined actions with this
% element and then calls itself recursively, taking the next element as
% its argument. |\fk@getcommasep@list| has to be called with
% |,\relax,|. Therefore, when all elements of the list have been
% used, |\relax| is the next, and the recursion ends.
%
% \begin{macrocode}
\newcounter{fk@commasep@argnumber}%
\def\fk@getcommasep@list#1#2#3#4#5#6{%
\setcounter{fk@commasep@argnumber}{0}%
#1
\def\fk@commasep@beforebranch{#2}%
\def\fk@commasep@firstelement{#3}%
\def\fk@commasep@furtherelements{#4}%
\def\fk@commasep@afterlastelement{#5\empty}%
\def\fk@commasep@aftereachelement{#6}%
\fk@@getcommasep@list
}
\def\fk@@getcommasep@list#1,{%
\stepcounter{fk@commasep@argnumber}%
\fk@commasep@beforebranch%
\ifx\relax#1%
\fk@commasep@afterlastelement%
% \end{macrocode}
%
% The counter has been incremented, and if we are already after the
% last element (so the argument was |\relax|), then
% |\fk@commasep@afterlastelement| (the fifth argument to the wrapper
% macro) is executed.
%
% The |\else|-branch means we have a real list element. We assign it (with
% whitespace removed) to |\fk@commasep@arg|. Then we check the counter
% wether we are working with the first element of the list, or with
% subsequent elements, and execute the respective commands (arguments
% number 3 and 4 to the wrapper macro).
%
% \begin{macrocode}
\else%
\FK@@sp@def\fk@commasep@arg{#1}%
\ifnum\c@fk@commasep@argnumber=1%
\fk@commasep@firstelement%
\else%
\fk@commasep@furtherelements%
\fi%
% \end{macrocode}
%
% After that, the sixth argument is executed which has been assigned to
% |\fk@commasep@aftereachelement|, and the macro calls
% itself again to take the next element.
%
% \begin{macrocode}
\fk@commasep@aftereachelement%
\expandafter\fk@@getcommasep@list%
\fi%
}
% \end{macrocode}
%
% Index entries for a sectioning level may contain commas, therefore
% using a comma separated list for them is not a good idea. We just copy
% the above definitions, but use |@--@| as the delimiter. Should you
% ever have to use this in an index entry, you need to define a command
% that typesets it and put this command in your optional argument, or
% the abbreviation definition.
%
% \begin{macrocode}
\newcounter{fk@atdashsep@argnumber}%
\def\fk@getatdashsep@list#1#2#3#4#5#6{%
\setcounter{fk@atdashsep@argnumber}{0}%
#1
\def\fk@atdashsep@beforebranch{#2}%
\def\fk@atdashsep@firstelement{#3}%
\def\fk@atdashsep@furtherelements{#4}%
\def\fk@atdashsep@afterlastelement{#5\empty}%
\def\fk@atdashsep@aftereachelement{#6}%
\fk@@getatdashsep@list
}
\def\fk@@getatdashsep@list#1§{%
\stepcounter{fk@atdashsep@argnumber}%
\fk@atdashsep@beforebranch%
\ifx\relax#1%
\fk@atdashsep@afterlastelement%
\else%
\FK@@sp@def\fk@atdashsep@arg{#1}%
\ifnum\c@fk@atdashsep@argnumber=1%
\fk@atdashsep@firstelement%
\else%
\fk@atdashsep@furtherelements%
\fi%
\fk@atdashsep@aftereachelement%
\expandafter\fk@@getatdashsep@list%
\fi%
}
% \end{macrocode}
%
% \subsubsection{Parsing lists in the optional argument}
% \label{sec:pars-lists-opti}
%
% Now we define a macro that uses |\fk@getcommasep@list| to parse the
% comma separated list in the optional argument of |\experiment| and
% |\subexperiment| (see \ref{sec:optarg-exp}). Its only declared argument
% is the sectioning level specifier (|exp| or |subexp|), but it should
% be called with the comma separated list (ending with |\relax,|)
% following the specifier. This specifier is stored in the macro
% |\fk@explevel| to make its usage more clear.
%
% First |\ifmore@thanone@item| is defined. It will be used to
% conditionally trigger actions after the last element. Before
% starting to iterate over the list, i.e. in the first argument to
% |\fk@getcommasep@list|, we set this to false.
%
% \begin{macrocode}
\newif\ifmore@thanone@item%
\def\fk@parse@optarg{%
\fk@getcommasep@list{%
\more@thanone@itemfalse%
}{%
}{%
% \end{macrocode}
%
% There's nothing to be done on every iteration before branching, so the
% second argument to |\fk@getcommasep@list| is empty. The third is
% executed for the first element in the list. We simply define the macro
% |\fk@current@tocentry| as this first element for later use.
% |\@onelevel@sanitize| changes |\fk@commasep@arg| to consist only of
% strings, not command sequences. This is necessary because hyperref
% will give an error with certain command sequences in bookmarks etc,
% e.g. with |\textit| which expands to |\protect\textit|. Wether this
% item will only be used for the toc and running title, or wether it
% additionally is put into the index (namely if there is only this first
% argument) cannot be decided now.
%
% \begin{macrocode}
\@onelevel@sanitize{\fk@commasep@arg}%
\protected@edef\fk@current@tocentry{\fk@commasep@arg}%
}{%

%
% If there is at least a second element\footnote{note that it
% doesn't make sense to use a list with two elements - there will
% be only one index entry, so you can just as well use only one.
% The only difference will be that you get the possibility to have
% different wording in the index entry \emph{and} the toc entry
% and the section heading, which I would try to avoid.}, we set
% |\ifmore@thanone@item| to |true|, then assign the currently
% processed list element to |\fk@currentarg|, appending a space only
% after we have made sure there will be no problems with fragile
% commands. Then we check wether it is an abbreviation for the
% current sectioning level. According to the result, we create the
% text to put in the index (|\fk@current@arg| itself or the text the
% abbreviation stands for). Then we call |\fk@buildindexlist| (see
% below) with it to add it to the index list for the current sectioning
% commands.

% \subsubsection{Building and using the list of index entries}
% \label{sec:building-list-index}
%
% The text to be indexed for every sectioning command is kept in a comma
% separated list, even if there is only one element. This list is build
% by prepending the new element to the expansion of the list. First, the
% lists (for experiments and subexperiments) are defined (as empty
% lists). The macros that call |\fk@buildindexlist| have to properly set
% |\fk@explevel| to |exp| or |subexp|, so that the new element gets into
% the right list.
%
% \begin{macrocode}
\def\fk@exp@indexlist{}%
\def\fk@subexp@indexlist{}%
\def\fk@buildindexlist#1{%
\def\@tmpA{exp}
\ifx\fk@explevel\@tmpA
\protected@edef\fk@exp@indexlist{#1§\fk@exp@indexlist}
\else
\protected@edef\fk@subexp@indexlist{#1§\fk@subexp@indexlist}
\fi
}
% \end{macrocode}
%
% To write index entries for each list element, we use
% |\fk@getcommasep@list| again. Here there is no difference between
% first and further elements, so we just define commands in the sixth
% argument, which is processed once for every element. The list never
% contains abbreviations, but always the text itself, so we just call
% |\fk@@writeindex| with the element.
%
% \begin{macrocode}
\def\fk@useindexlist{%
\fk@getatdashsep@list{}{}{}{}{}{%
\fk@@writeindex{\fk@atdashsep@arg}%
}%
}%
% \end{macrocode}
%
% |\fk@@writeindex| handles the differences in index writing for
% experiments and subexperiments. If a new experiment is started (or
% closed), then an index for every list element has to be written:
%
% \begin{macrocode}
\def\fk@@writeindex#1{%
\def\@tmpA{exp}%
\ifx\fk@explevel\@tmpA%
\fk@writeindex{#1}%
\else%
% \end{macrocode}
%
% If we are writing index entries for a subexperiment, things get more
% complicated, because the experiment \emph{and} the subexperiment
% might have more than one associated index entry. Therefore we have to
% iterate over both |\fk@exp@indexlist| and |\fk@subexp@indexlist|. To
% achieve this, for a subexperiment (where |\fk@explevel| is |subexp|),
% |\fk@useindexlist| will be called with
% |\fk@|\textit{exp}|@indexlist|, and |\fk@parselevel| is set
% to |exp|. When |\fk@openindex| is called with explevel
% |subexp|, but parselevel |exp|, its argument is
% assigned to |\fk@current@expname|, the parselevel is changed to
% |subexp|, and |\fk@useindexlist| is called again with
% |\fk@|\textit{subexp}|@indexlist|. When doing this,
% |\fk@openindex| will be called again, but since now the parselevel
% is |subexp|, we get into the other branch. After processing
% |\fk@subexp@indexlist| is finished, we have to continue processing
% the next elements in |\fk@exp@indexlist|. Therefore we reset the
% parselevel to |exp|.
%
% \begin{macrocode}
\ifx\fk@parselevel\@tmpA% we are iterating over the current list
% of experiments
\protected@edef\fk@current@expname{#1}
\def\fk@parselevel{subexp}
\expandafter\fk@useindexlist\fk@subexp@indexlist\relax§%
\def\fk@parselevel{exp}
\else
% \end{macrocode}
%
% When processing the subexperiment's index list, we get into this
% branch, and now for every subexperiment index element an entry is made
% for the current meaning of |\k@current@expname|.
%
% \begin{macrocode}
\fk@writeindex{\fk@current@expname!#1}%
\fi
\fi%
}%
% \end{macrocode}
%
% The previous procedure made use of |\fk@writeindex| which is never
% defined itself. It is |\let| to |\fk@openindex| or |\fk@closeindex|,
% depending on where it is called. The first writes index entries which
% open a range, i.e. §\index{text|(}§, the second closes the ranges
% again (§\index{text|)}§).
%
% \begin{macrocode}
\def\fk@openindex#1{\index{#1|(}}%)
\def\fk@closeindex#1{\index{#1|)}}%)
% \end{macrocode}
%
% \subsection{Checking for abbreviation usage}
% \label{sec:check-abbr-usage}
%
% The next few macros are used to check wether an abbreviation or a
% text was used as the argument of |\(sub)experiment|. First a little
% helper macro:
%
% \begin{macrocode}
\def\muST@bE@emPTy{\message{Numquam videbor}}%
% \end{macrocode}
%
% |\fk@checkifabbrev@arg| is defined so that its first argument ends
% with a space and the second only at the \&-sign; it is called with a
% space appended to the item to check. Thus, if the second argument
% isn't empty, there was a space in the item itself, and it cannot be an
% abbreviation. If the second argument is empty, we check wether we have
% an abbreviation using |\fk@checkfirst|:
%
% \begin{macrocode}
\newif\ifabbrev@defined%
\def\fk@checkifabbrev@arg #1 #2{%
\ifx\muST@bE@emPTy#2\muST@bE@emPTy%
\protected@edef\@tmpA{#1\space}%
\expandafter\fk@checkfirst\@tmpA{#3}%
\else%
\abbrev@definedfalse%
\fi%
}%
% \end{macrocode}
%
% The first argument of |\fk@checkfirst| ends at the first space - note that
% |\fk@currentarg| was defined with a space appended. This is necessary because
% we have to be able to cut |\fk@currentarg| in words, not in single
% characters. The second argument to |\fk@checkfirst| specifies the
% level we are on (experiment or subexperiment).
%
% The macro now checks wether the requested abbreviation has been
% defined, and sets the conditional accordingly:
%
% \begin{macrocode}
\def\fk@checkfirst #1 #2{%
\@ifundefined{#2@#1}{\abbrev@definedfalse}{\abbrev@definedtrue}%
}%
% \end{macrocode}
%
% \subsection{Closing the index entries}
% \label{sec:closing-entries}
%
% This macro, |\fk@close@labindex|, will be used in a couple of
% circumstances to close open index ranges. First we make
% |\fk@writeindex| produce entries that close the index ranges. If there
% has been no experiment on the current |\labday|, then |\fk@explevel|
% is undefined, and we don't do anything. Otherwise the experiment level
% is determined, and |\fk@@close@labindex| is called appropriately.
%
% \changes{v1.0a}{2003/04/29}{removed wrong index closing for
% subexperiments}
% \begin{macrocode}
\def\fk@close@labindex{%
\let\fk@writeindex\fk@closeindex%
\@ifundefined{fk@explevel}{}{%
% \end{macrocode}
%
% If |\fk@explevel| is |exp|, then we need to close any open experiment
% \emph{and} subexperiment index ranges. We first handle the
% subexperiment. Before we call the macro that does it, we set
% |\fk@explevel| to |subexp| and |\fk@parselevel| to |exp|, as required
% by |\fk@@writeindex| (see \ref{sec:building-list-index}), and after
% that we reset it to |exp| to close the experiment ranges themselves.
% If |\fk@explevel| is |subexp|, however, we just call the closing
% macro:
%
% \begin{macrocode}
\def\@tmpA{exp}%
\ifx\fk@explevel\@tmpA%
\def\fk@parselevel{exp}%
\def\fk@explevel{subexp}%
\fk@@close@labindex%
\def\fk@explevel{exp}%
\fk@@close@labindex%
\else%
\fk@@close@labindex%
\fi%
}%
}%
% \end{macrocode}
%
% |\fk@@close@labindex| calls |\fk@useindexlist| -- always with
% the argument |\fk@exp@indexlist| -- and then flushes the list
% for the current explevel.
%
% \begin{macrocode}
\def\fk@@close@labindex{%
\expandafter\fk@useindexlist\fk@exp@indexlist\relax§%
\expandafter\def\csname fk@\fk@explevel @indexlist\endcsname{}%
}
% \end{macrocode}
%
%
% \section[Defining the new sectioning commands]{Defining the new
% sectioning commands \textbackslash\texttt{labday} and
% \textbackslash\texttt{(sub)experiment}}
% \label{sec:newsectcommands}
%
% First we define the counters. Footnote numbers are reset every day.
%
%\changes{v1.1a}{2003/06/13}{Let footnote numbering be reset every day}
% \begin{macrocode}
\newcounter{labday}
\newcounter{experiment}[labday]
\newcounter{subexperiment}[experiment]
\@addtoreset{footnote}{labday}
% \end{macrocode}
%
% If somebody uses |\subsubsection|, this has to be reset
% properly. The marks have to be let to |\@gobble| initially:
%
% \begin{macrocode}
\@addtoreset{subsubsection}{subexperiment}
\let\experimentmark\@gobble
\let\subexperimentmark\@gobble
% \end{macrocode}
%
% The level of sections is designed to be used to classify an
% experiment. The level
% below that, usually subsection, is redefined as |\subexperiment|. It
% should be used for things like ``rationale'', ``preparations'', or
% ``evaluation'', or the like, and will also get into the toc and index:
%
% \begin{macrocode}
\setcounter{tocdepth}{3}
% \end{macrocode}
%
% Thus, chapters, sections and subsections go into the toc besides
% labdays, experiments and subexperiments, but this should only be
% used for things in |\frontmatter| or at the start of |\mainmatter|.
%
% Besides that, nothing is done in this class to format table of
% contents and index. This can be done individually with different
% packages on CTAN.
%
%\subsection{Defining experiment}
%\label{sec:defining-experiment}
%
% \begin{macrocode}
\def\experiment{%
% \end{macrocode}
%
% The first thing we do is close the index entry for the preceding
% |\experiment| and |\subexperiment|. Thus, this will be done before a
% potential page break. The macro |\fk@close@labindex| will be defined
% later, see \ref{sec:closing-entries}. Then we set
% |\iflower@sectionlevel| to |false| -- this might have been set true by
% a previously used |\subsubsection|, were no indexing should be done.
%
% \begin{macrocode}
\def\fk@explevel{exp}
\fk@close@labindex%
\lower@sectionlevelfalse%
% \end{macrocode}
%
% One can use the unstarred form with abbreviations, and with free text,
% too. However, if there is more than just text in the free text, e.g. a
% command like |\textit{...}|, then there will be an error message from
% \TeX\ which is hard to understand. Therefore it is strongly
% recommended to use free text only with the starred form.
%
% We descriminate between the starred and unstarred forms and first
% define the unstarred version: It checks wether there is an optional
% argument in square brackets and calls the respective macros:
%
% \begin{macrocode}
\@ifstar{\@sexperiment}{\@experiment}%
}
\def\@experiment{%
\@ifnextchar [{\opt@arg@experiment}{\nopt@arg@experiment}%
}
% \end{macrocode}
%
% \subsubsection{\textbackslash\texttt{experiment} without optional argument}
%
% First the case of no optional argument is defined. Either the one
% argument is an abbreviation as defined by the user command
% |\newexperiment|, or it is of free form. Checking which is not
% straightforward, because we cannot simply put a whole sentence,
% possibly with markup macros, into an |\@ifundefined|-command.
%
% \begin{macrocode}
\def\nopt@arg@experiment#1{%
\def\fk@currentarg{#1 }\@onelevel@sanitize{\fk@currentarg}%
\expandafter\fk@checkifabbrev@arg\fk@currentarg&{long@exp}%
% \end{macrocode}
%
% The first line in the definition has the effect that |\fk@currentarg|
% contains the argument text, but everything is read as text, not as a
% macro, even if it looks like it. Then |\fk@checkifabbrev@arg| is called
% with this string of characters and (possibly) spaces as an argument
% and an arbitrary delimiter, here \&. This macro, defined below,
% changes the conditional |\ifabbrev@defined|.
%
% \begin{macrocode}
\ifabbrev@defined%
% \end{macrocode}
%
% The case with an abbreviation, so we have to manually assign short
% and long forms for |\@startsection|, and make sure that the short
% form gets into the index. Indexing is done by calling
% |\fk@buildindexlist| with the meaning of the abbreviation. It will
% automatically used by |\addcontentsline|. The actual arguments for
% |\@startsection| are just a copy of the |\section|-definition from
% scrbook.cls.
%
% \begin{macrocode}
\fk@buildindexlist{\csname short@exp@#1\endcsname}%
\@startsection{experiment}{1}{\z@}%
{-3.5ex \@plus -1ex \@minus -.2ex}%
{2.3ex \@plus.2ex}%
{\raggedsection\normalfont\sectfont\nobreak\size@section\nobreak}%
[\@nameuse{short@exp@#1}]{\@nameuse{long@exp@#1}}%
\else%
% \end{macrocode}
%
% |\else| is the case where the user just uses
% the free form (or mistyped the abbreviation
% - but that will show up in the dvi/pdf
% file). |\@startsection| will |\@dblarg| the parameter itself.
%
% \begin{macrocode}
\expandafter\fk@buildindexlist{\fk@currentarg}
\@startsection{experiment}{1}{\z@}%
{-3.5ex \@plus -1ex \@minus -.2ex}%
{2.3ex \@plus.2ex}%
{\raggedsection\normalfont\sectfont\nobreak\size@section\nobreak}%
{#1}%
\fi%
}%
% \end{macrocode}
%
% \subsubsection{\textbackslash\texttt{experiment} with an optional argument}
% \label{sec:optarg-exp}
%
% Now comes the case where |\experiment| was called with an optional
% argument. The optional argument may consist of
% \begin{itemize}
% \item One arbitrary sentence with formatting \emph{without} commas, or
% \item one previously defined abbreviation, or
% \item a comma separated list of items. The items should usually be
% abbreviations, the first may be an arbitrary sentence (with formatting).
% \end{itemize}
% In the latter case, the first one is used for the table of contents
% and the running title, but \emph{not} for the index; the following are
% put in the index. All this is achieved by calling
% |\fk@parse@optarg|, after setting its parselevel to exp.
%
% \begin{macrocode}
\def\opt@arg@experiment[#1]#2{%
\fk@parse@optarg#1,\relax,%
% \end{macrocode}
%
% The checks regarding abbreviations get more complicated
% here, we have to check the first item in the optional argument -- this is
% done by the macro |\fk@parse@optarg|~--, and the long argument.
%
% \begin{macrocode}
\ifabbrev@defined%
\def\fk@currentarg{#2 }\@onelevel@sanitize{\fk@currentarg}%
\expandafter\fk@checkifabbrev@arg\fk@currentarg&{long@exp}%
\ifabbrev@defined%
% \end{macrocode}
% This is the strange, but working case with two predefined
% forms. We have to check wether they are equal. In fact the
% user may use different abbreviations as long as the short
% forms expand to the same index/toc entry.
%
% The check works like this: The first |\expandafter| delays the |\ifx|
% conditional until the next token, |\csname|, has been
% expanded. Expansion of |\csname|, however, scans for an
% |\endcsname|, but before it gets there (to the first one), it
% encounters the second |\expandafter|. Therefore, first the last
% |\csname| is expanded, yielding the macro |\short@exp@|, then the
% first is expanded, and we get\\
% |\ifx\short@exp@\short@exp@|.

% \subsection{Defining labday}
% \label{sec:defining-labday}
%
% In mainmatter, |\labday| replaces chapter. (|\chapter| may still be
% used and will get a toc entry, e.g. after |\backmatter|). |\labday| is
% an extended |\addchap| (i.e. an un-numbered |\chapter| with toc entry
% and assignment of a running headline) which additionally sets the
% closing index entry for the preceding |\(sub)experiment|. After
% closing, |\k@explevel| is made undefined, so that addcontentsline
% won't try to open index ranges.
%
% \begin{macrocode}
\newcommand*{\labday}{%

%
%
% \subsection{Adjusting subsubsection}
% \label{sec:adj-subsubsection}
%
% If somebody uses lower sectioning levels than |\subexperiment|, the
% index lists are not affected, and thus |\addcontentsline| would again
% open the index entries for the last |\subexperiment|. To avoid this,
% we extend |\subsubsection|; it now sets the conditional
% |\iflower@sectionlevel| to true. This will be checked by |\addcontentsline|.

%
% \subsection{Section numbering, floats and the table of contents}
% \label{sec:adjust-section-number}
%
% Since the days will not be numbered, we want to also change the
% numbering scheme for the new sectioning commands:

% \begin{macrocode}
\renewcommand*\theexperiment{\@arabic\c@experiment}%
\renewcommand*\thesubexperiment{%
\theexperiment.\@arabic\c@subexperiment}%
% \end{macrocode}
%
% And for consistency also for the lower levels -- nobody will ever need
% these numbered, will one?
%
% \begin{macrocode}
\renewcommand*\thesubsubsection{%
\thesubexperiment.\@arabic\c@subsection}%
\renewcommand*\theparagraph{%
\thesubsubsection.\@arabic\c@paragraph}%
\renewcommand*\thesubparagraph{%

\@addtoreset{table}{labday}%
\renewcommand*\thefigure{%
\@arabic\c@figure}%
\renewcommand*\thetable{%
\@arabic\c@table}%
% \end{macrocode}
%
%
% To be able to print a table of contents, we have to define
% |\contentsline| for labday, experiment and subexperiment. We just copy the
% definitions from |\chapter| and |\(sub)section|:

%
% If |\experiment| or |\subexperiment| are called, then
% |\addcontentsline| is extended to open the index range entries
% (closing is done by |\fk@close@labindex|, see above).
%
% Redefining is only done \emph{here} if we do not use |hyperref.sty|.
% If the |hyperref| option has been specified, it is delayed until after
% this package has been loaded, see section \ref{sec:hyperref-compat}.
% What we do here in any case is define a macro that will do the real
% defining of |\addcontentsline|.

%
% First, we call all the old commands. After that, we apply the changes,
% starting with a bunch of checks: First wether we are called from a
% sectioning command (writing to |toc|), not by a caption of a figure or
% table; then wether |\fk@explevel| is defined (i.e. wether we are not
% called by |\part|, |\labday| or a traditional sectioning command
% outside mainmatter). And last wether we are not called by
% subsubsection or lower.

%
%\subsection{Making sure the last index range is closed}
%
% Since closing of the index entries is usually done by the subsequent
% call of |\(sub)experiment|, the last would never be closed. The
% closing has to be done at the begin of the appendix if there is one,
% or at the end of mainmatter, if |\backmatter| is called, or at last at
% the end of the document. The user should still be able to call
% |\appendix| and |\backmatter| in arbitrary order, or not at all. To
% decide at which place we close, we define a new conditional which is
% initialized to be false. Then we define the command
% |\fk@close@labindex| to close the index entries, if one is open (i.e.
% if |\fk@current@(sub)expname| is not |\relax|). After closing, we
% |\let| the index names to |\relax|.
%
% The |\appendix| command is extended to call |\fk@close@labindex| if
% the conditional is still false, so is |\backmatter|. Additionally,
% after closing the index entries |\fk@explevel| is made undefined, so
% that subsequent calls of |\addcontentsline| don't even try to use
% the (albeit empty) index lists.

\title{labbook.cls, eine \LaTeX-Klasse zum F"uhren von experimentellen
Laborjournalen, Version 1.1}
\author{Frank K"uster}
\date{2003-05-20}
\maketitle
\begin{abstract}
Diese Klasse soll es erm"oglichen, Laborb"ucher mit chronologischen
Aufzeichnungen "uber Experimente mit \LaTeX\ zu f"uhren. Die neuen
Seiten werden einfach jeden Tag hinten angeheftet, aus den
Gliederungselementen wird ein Experiment-Index generiert, um das
Auffinden von bestimmten Experimenten zu erleichtern. Durch
unterschiedliche Seitennummerierung kann der Vorspann (Index,
Inhalt, Abkürzungsverzeichnis) unabhängig vom Hauptteil verl"angert
werden. Die Klasse basiert auf der KOMA-Script-Klasse
|scrbook.cls|. Es k"onnen daher alle Merkmale dieser Klasse
verwendet werden -- die Lekt"ure des |scrguide|, der
KOMA-Script-Dokumentation, wird daher sehr empfohlen.
\end{abstract}
\tableofcontents
\section{Generelles}
\subsection{Rechtliches}
Die F"uhrung von Laborb"uchern ist teilweise gesetzlich geregelt, oft
stellen Institutionen zur Forschungsf"orderung weitere Anforderungen.
In der Regel ist es daher \emph{nicht} erlaubt, ein Laborjournal
lediglich in elektronischer Form zu f"uhren; teilweise sind gebundene
B"ucher vorgeschrieben. Allerdings scheint es auch dort "ublich zu
sein, die Notizen, die man w"ahrend der Experimente auf losen
Bl"attern, in Computerdateien oder einem "`Schmierbuch"' gef"uhrt hat,
mehr oder weniger regelm"a"sig ins gebundene Laborjournal zu
"ubertragen.
Aus diesem Grund scheint es mir vertretbar, mit einer elektronischen
und einer parallelen ausgedruckten Fassung des Laborjournals zu
arbeiten. Bei Bedarf kann die ausgedruckte Fassung geheftet oder
gebunden werden, eine auf CD-ROM gebrannte Version sollte einem Buch
an Beweiskraft nicht nachstehen. Dem stehen die gro"sen Vorteile v.a. einer
PDF-Fassung gegen"uber: Volltextsuche, einfache Einbindung von
Graphen und Bildern, M"oglichkeit der Verlinkung von Datendateien etc.
\subsection{Merkmale}
\label{sec:features}
\begin{description}
\item[Basisklasse] |labbook.cls| basiert auf der KOMA-Script-Klasse
|scrbook.cls| und bietet daher alle Möglichkeiten dieser Klasse, vom
Seitenlayout über Kopfzeilengestaltung und Absatzauszeichnung bis
hin zu Variationen des Layouts von \textit{floats} und
Randbemerkungen. Die Lektüre des scrguide wird sehr empfohlen!
\item[Gliederung] Die Gliederung erfolgt zun"achst chronologisch,
statt |\chapter| wird |\labday| verwendet. Innerhalb eines Tages
wird nach Experimenten untergliedert -- das kann eine vollständige
Messung von der Planung bis zur Auswertung sein, aber auch ein
Arbeitsgang eines mehrere Tage dauernden Versuchs. |\experiment|
steht auf der Ebene von |\section|, zusätzlich steht
|\subexperiment| auf der |\subsection|-Ebene zur Verfügung. Darunter
gibt es die "ublichen Gliederungsebenen, auch wenn eine sehr tiefe
Schachtelung wenig sinnvoll erscheint -- man beachte das
|\minisec|-Kommando von KOMA-Script.
\item[Index und Inhaltsverzeichnis] Wegen der chronologischen Gliederung ist ein
traditionelles Inhaltsverzeichnis nicht ausreichend, besonders wenn
Versuche in einem zusammenh"angenden Experiment an verschiedenen
Tagen durchgef"uhrt werden. Daher wird zusätzlich ein Index
ausgegeben. Der Index wird aus den Inhaltsverzeichnis-Einträgen der
Abschnittsbefehle erstellt. Als Argument für |\experiment| und
|\subexperiment| kann man auch vorher definierte Abkürzungen
verwenden. Dadurch soll die konsistente Erstellung des Index
erleichtert werden. Außerdem können einem Experiment mehrere
Indexeinträge zugeordnet werden.
\item[hyperref-Integration] Die Klasse arbeitet gut mit dem Paket
|hyperref.sty| zur Erstellung von pdf-Dateien mit
Navigationsfunktionen zusammen.
\end{description}
\section{Benutzung}
\label{sec:usage}
\subsection{Initialisierung}
\label{sec:options}
Wenn man hyperref verwenden möchte \emph{muss} man die Klassenoption
|hyperref| angeben:
\begin{verbatim}
\documentclass[hyperref]{labbook}
\end{verbatim}
Danach kann man hyperref und andere Pakete in der jeweils passenden
Reihenfolge laden. Wird hyperref geladen, ohne die Option anzugeben,
dann überschreibt es einige Änderungen, die in dieser Klasse in
\LaTeX-Interna eingefügt werden. Umgekehrt werden diese Änderungen gar
nicht erst durchgeführt, wenn man die Option |hyperref| angibt, aber
das Laden des Paketes vergisst! Bei der Verwendung von hyperref
sollte man außerdem die KOMA-Option |idxtotoc| in Erwägung ziehen: Der
Index wird nämlich nicht nur in das Inhaltsverzeichnis aufgenommen,
sondern auch in die PDF-Bookmarks.
Ansonsten werden derzeit einfach alle Optionen an scrbook
durchgereicht. Die Verwendung von |openany| bietet sich an, damit
Labortage auf jeder Seite beginnen können.
\section{Gliederungsbefehle}
\label{sec:gliederungsbefehle}
subsection{\textbackslash\texttt{labday}}
label{sec:labday}
\DescribeMacro{\labday} Der Befehl |\labday| kann verwendet werden, um
eine nicht nummerierte "Uberschrift zu erzeugen. Ihr Text (bzw. der des
optionalen Arguments) wird ins Inhaltsverzeichnis aufgenommen und als
lebender Kolumnentitel gesetzt. In der Regel wird man einfach das
Datum, vielleicht mit dem Wochentag, verwenden. |\labday| kümmert
sich auch um die Indexeinträge der untergeordneten Gliederungspunkte;
man sollte es nur innerhalb von mainmatter verwenden. Intern wird
|\addchap| aufgerufen, es gibt keine Sternform und kein optionales
Argument.
\subsection{\textbackslash\texttt{experiment} und
\textbackslash\texttt{subexperiment}: Einfache Verwendung}
\label{sec:exper-und-subexp}
\DescribeMacro{\experiment} Innerhalb eines Tages k"onnen nummerierte
"Uberschriften für einzelne Experimente mit
\begin{verbatim}
\experiment[]{}
\end{verbatim}
erzeugt werden. Ihr Text (bzw. der des optionalen Arguments) wird
nicht nur ins Inhaltsverzeichnis und den Seitenkopf geschrieben,
sondern auch in den Index. Dieser erleichtert die Orientierung,
besonders wenn Experimente mehrfach oder "uber mehrere Tage hinweg
durchgef"uhrt werden. Die Indexeintr"age geben nicht nur die Seiten
des Beginns jedes Experiments an, sondern den ganzen Seitenbereich,
und fassen zusammenhängende Bereiche des gleichen Experiments an
unterschiedlichen Tagen zusammen.
Beachten Sie, dass man im optionalen Argument keine Kommas verwenden
darf, weil es auch eine durch Kommas abgetrennte Liste enthalten kann
(s.\,u.). Wenn Sie doch ein Komma benötigen, schließen Sie das
optionale Argument nochmals in geschweifte Klammern ein:
\begin{verbatim}
\experiment[{eins, zwei, drei}]{Die Eins, die zwei und die Drei}
\end{verbatim}
\DescribeMacro{\subexperiment} Das selbe gilt f"ur die darunter
liegenden |\subexperiment|-Eintr"age. Sie sind f"ur Untergliederungen
der Art "`Planung, Durchf"uhrung, Auswertung"' oder "`Herstellung,
Reinigung, Messung"' vorgesehen.
\subsection{Fortgeschrittene Verwendung: Abk"urzungen}
\label{sec:abkurzungen}
\DescribeMacro{\newexperiment} Wenn man für das gleiche Experiment an
unterschiedlichen Stellen leicht unterschiedliche Formulierungen (oder
Schreibungen) wählt, erhält man unterschiedliche Indexeinträge. Um
dies zu vermeiden, kann man sich Abk"urzungen für häufig auftretende
Experimente definieren. Dies geschieht mit dem Makro
|\newexperiment{}{}{}|
Dabei bezeichnet || die Abk"urzung, mit der man auf die
definierte || und || zugreifen kann (letztere für
Index, Inhaltsverzeichnis und Kolumnentitel). Der Text der Abk"urzung
ist dabei \emph{ohne} vorangestellten Backslash einzugeben, also als
|\experiment{abk}|! Die Abk"urzungen d"urfen außer der Tilde
(\textasciitilde), dem Komma und Leerzeichen sämtliche Zeichen
enthalten.
\DescribeMacro{\newsubexperiment} Für |\subexperiment| steht ein
analoges Makro, |\newsubexperiment|, zur Verfügung.
Bei jeder Verwendung eines dieser Makros wird "uberpr"uft, ob die
gew"unschte Abk"urzung bereits verwendet wurde, und gegebenenfalls ein
Fehler erzeugt. Gleichlautende Abk"urzungen f"ur |\experiment| und
|\subexperiment| sind grunds"atzlich m"oglich, d"urften aber nur
Verwirrung stiften (beim Benutzer, nicht bei \TeX). Wird das dritte
Argument dieser Makros leer gelassen, so wird die Langform auch f"ur
Index und Inhaltsverzeichnis verwendet.
|\experiment| und |\subexperiment| k"onnen wie |\section| mit oder
ohne optionales Argument verwendet werden, und zwar sowohl mit v"ollig
frei gew"ahlten "Uberschriften (Kurz- und Langform) als auch mit einer
Abk"urzung. Die Kombination einer Abk"urzung im optionalen Argument
und einer variierten, freien Langform im Hauptargument ist m"oglich,
die Verwendung eines frei formulierten optionalen Arguments mit einer
Abk"urzung im Pflichargument f"uhrt jedoch zu einem Fehler, denn die
Abk"urzung legt ja bereits einen Index- und Verzeichniseintrag fest.
Die Verwendung zweier unterschiedlicher Abk"urzungen in optionalem und
Pflichtargument ist m"oglich, wenn sie beide zum selben Indexeintrag
f"uhren.
\subsection{Mehrfache Indexeinträge}
Manchmal führt man zusammenpassende Arbeitschritte für verschiedene
Experimente parallel aus, das verkompliziert die Indexeinträge.
Stellen Sie sich z.\,B. vor, Sie hätten mit einer Screening-Methode
die Substanzen A152 und B96 aus einer kombinatorischen Bibliothek als
vielversprechende Medikamente identifiziert. Als nächstes möchten Sie
deren exakte Struktur, Zusammensetzung oder Sequenz verifizieren und
eine Präparationsmethode für etwas größere Mengen entwickeln.
Wahrscheinlich können Sie Zeit sparen, indem Sie einige dieser
Schritte für beide Substanzen parallel ausführen, aber dann erhalten
Sie einen Index mit Einträgen wie "`A152 und B96, Sequenzierung"' --
und zwei Monate später sollen Sie sich erinnern, ob sie B96 zusammen
mit A152 sequenziert haben oder stattdessen in der folgenden Woche mit
A43 und C12. Daher wäre es praktisch, für das Experiment
"`Sequenzierung von A152 und B96"' zwei Indexeinträge zu erhalten,
nämlich "A152, Sequenzierung"' und "B96, Sequenzierung"'. Und genau
das können Sie einfach erzeugen.
\DescribeMacro{\subexperiment}\DescribeMacro{\experiment}
Denn die Syntax von |\experiment| und |\subexperiment| erlaubt es,
eine durch Kommata abgetrennte Liste im optionalen Argument zu
verwenden. Das erste Element wird für das Inhaltsverzeichnis und die
Kolumnentitel verwendet, und die folgenden Elemente liefern
Indexeinträge. Angenommen, Sie haben die Abkürzungen A152-seq und
B96-seq definiert, dann brauchen Sie nur zu schreiben:
\begin{verbatim}
\experiment[Sequenzierung A152 und B96, A152-seq,
B96-seq]{Sequenzierung der Inhibitor-Kandidaten A152 und B96}
\end{verbatim}
und Sie erhalten was Sie wünschen. Leerzeichen vor und nach den
Kommata werden ignoriert. Sie können überall Abkürzungen oder freien
Text wählen, obwohl für die Indexeinträge wahrscheinlich nur
Abkürzungen wirklich sinnvoll sind.
