%
% Over the decades, \TeX\ has gained popularity across a large number of disciplines. Although originally designed as a mere typesetting system, packages such as \pkg{pgf}\footnote{Tantau, T. (2010). The \TikZ\ and \textsc{pgf} packages. \url{http://ctan.org/tex-archive/graphics/pgf/}.} and \pkg{pstricks}\footnote{van Zandt, T., Niepraschk, R., and Voß, H. (2007). PSTricks: PostScript macros for Generic \TeX. \url{http://ctan.org/tex-archive/graphics/pstricks}.} have strongly extended its \textit{drawing} abilities. Thus, one can create complicated charts that perfectly integrate with the text.
%
-% Texts on molecular biology include a range of special graphs, e.\,g. multiple sequence alignments, membrane protein topologies, DNA sequencing chromatograms, plasmid maps, protein domain diagrams and others. The \pkg{texshade}\footnote{Beitz, E.

-% The \pkg{pgfmolbio} package aims at becoming such a purist solution. In its first development release, \pkg{pgfmolbio} is able to read DNA sequencing files in standard chromatogram format (\file{.scf}) and draw the corresponding chromatogram using routines from \pkg{pgf}'s \TikZ\ frontend. In order to convert the data from the \file{scf} input file to an image, \pkg{pgfmolbio} relies on the Lua scripting language implemented in Lua\TeX. Consequently, the package will not work with traditional engines like pdf\TeX.

%
% Since this is a development release, \pkg{pgfmolbio} presumably includes a number of bugs, and its commands and features are likely to change in future versions. Moreover, the current version is far from complete, but since time is scarce, I am unable to predict when (and if) additional functions become available. Nevertheless, I would greatly appreciate any comments or suggestions.

%
-% The package is divided into \textit{modules}, each of which produces a certain type of graph. Currently, only one \ometa{module} is available: \opt*{chromatogram} allows you to draw DNA sequencing chromatograms as obtained by the Sanger sequencing method. Thus, the only sensible way of including the package is currently |\usepackage[chromatogram]{pgfmolbio}|.
+% The package is divided into \textit{modules}, each of which produces a certain type of graph. Currently, three \ometa{module}s are available:
+% \begin{itemize}
+% \item \module{chromatogram} (chapter~\ref{cha:Chromatogram}) allows you to draw DNA sequencing chromatograms obtained by the Sanger sequencing method.
+% \item \module{domains} (chapter~\ref{cha:Domains}) provides macros for drawing protein domain diagrams and is also able to read domain information from files in Uniprot or general feature format.
+% \item Furthermore, \module{convert} (chapter~\ref{cha:Convert}) is used with one of the modules above and generates ``pure'' \TikZ\ code suitable for \TeX\ engines lacking Lua support.

The documentation for the Staden package\footnote{\url{http://staden.sourceforge.net/}} describes the current version of the \file{scf} format in detail.

+%
+% \section{Overview}
+% \label{sec:DomOverview}
+%
+% Protein domain diagrams appear frequently in databases such as Pfam\footnote{Finn, R.\,D., Mistry, J. \textit{et al.} (2010). The Pfam protein families database. \textit{Nucleic Acids Res.} \textbf{38}, D211--D222.} or \textsc{prosite}\footnote{Sigrist, C.\,J.\,A., Cerutti, L. \textit{et al.} (2010). \textsc{prosite}, a protein domain database for functional characterization and annotation. \textit{Nucleic Acids Res.} \textbf{38}, D161--D166.}. Domain diagrams are often drawn using standard graphics software or tools such as \textsc{prosite}'s MyDomains image creator\footnote{\url{http://prosite.expasy.org/mydomains/}}. However, the \module{domains} module provides an integrated approach for generating domain diagrams from \TeX\ code or from external files.

+% \section{Domain Diagrams and Their Features}
+% \label{sec:DomDiagrams}
+%
+% \DescribeEnv[\meta{features}]{pmbdomains}[<key-value list>]{<sequence length>}
+% Draws a domain diagram with the \meta{features} given. The \ometa{key-value list} configures its appearance. \meta{sequence length} is the total number of residues in the protein. (Although you must eventually specify a sequence length, you may actually leave the mandatory argument empty and use the \opt{sequence length} key instead; see section~\ref{sec:DomFileInput}).
+%
+% You can put a |pmbdomains| environment into a |tikzpicture|, but you also may use the environment on its own. \pkg{pgfmolbio} checks whether it is surrounded by a |tikzpicture| and adds this environment if necessary.
+%
+% \DescribeOption{domains/}{name}{Protein}<text>
+% The name of the protein, which usually appears centered above the diagram.
+%
+% \DescribeOption{domains/}{show name}{true}<boolean>
+% Determines whether both the name and sequence length are shown.
+%
+% \DescribeMacro\addfeature[<key-value list>]{<type>}{<start>}{<stop>}
+% Adds a feature of the given \meta{type} to the current domain diagram (only defined inside |pmbdomains|). The feature spans the residues from \meta{start} to \meta{stop}. These arguments are either numbers, which refer to residues in the relative numbering scheme, or numbers in parentheses, which refer to absolute residue numbers (see section~\ref{sec:DomGeneralLayout}).
+%
+% \DescribeOption{domains/}{description}{\textrm{(none)}}<text>
+% Sets the feature description (Example~\ref{exa:DomTikzpicture}).

+% The baselines of consecutive lines (i.\,e., the main chain $y$-coordinates) are separated by \meta{factor} times the value of \opt{y unit}. In Example~\ref{exa:DomResiduesPerLine}, you see four lines, each of which contains up to 30~residues. Note how domains are correctly broken across lines. Furthermore, the baselines are $2 \times 4 = 8$~mm apart.

+%
+% \DescribeOption{domains/}{residue numbering}{auto}<numbering scheme>
+% A protein's amino acid residues are usually numbered consecutively starting from~1. However, there are different numbering schemes. For example, residue numbering in a serine protease related to chymotrypsin typically follows the numbering in chymotrypsinogen\footnote{Bode, W., Mayr, I. \textit{et al.} (1989). The refined 1.9 Å crystal structure of human $\alpha$-thrombin: interaction with \textsc{d}-Phe-Pro-Arg chloromethylketone and significance of the Tyr-Pro-Pro-Trp insertion segment. \textit{EMBO J.} \textbf{8}(11), 3467--3475.}. The target protease sequence is aligned to the chymotrypsinogen sequence, and equivalent residues receive the same number. Insertions into the target sequence are indicated by appending letters to the last aligned residue (e.\,g., 186, \textit{186A}, \textit{186B}, 187), whereas gaps in the target sequence cause gaps in the numbering (e.\,g., 124, 125, 128, 129).
+%
+% In \pkg{pgfmolbio}, you can specify a relative \meta{numbering scheme} via the \opt{residue numbering} key. The keyword |auto| indicates that residues are numbered from 1 to (sequence length), i.\,e. absolute and relative numberings coincide. This is the case in all examples above. The complete syntax for the key is
+% \begin{quote}
+% \meta{numbering scheme} := \MacroArgs{<range>[','<range>', ...']}\\
+% \meta{range} := \MacroArgs<start>'-'<end>' | '<start>\\
+% \meta{start} := \MacroArgs<number>' | '<number><letter>\\
+% \meta{end} := \MacroArgs<number>' | '<letter>
+% \end{quote}
+%
+% Example~\ref{exa:DomResidueNumbering} shows a custom \meta{numbering scheme}, in this case for kallikrein-related peptidase 2 (KLK2), a chymotrypsin-like serine proteases. (In the following explanation, the subscripts `abs' and `rel' denote absolute and relative numbering, respectively).
+% \begin{itemize}
+% \item Residue 1\textsubscript{abs} is labeled 16\textsubscript{rel}, residue 2\textsubscript{abs} is labeled 17\textsubscript{rel} etc. until residue 24\textsubscript{abs}, which is labeled 39\textsubscript{rel} (range |16-39|).
+% \item Residue 25\textsubscript{abs} corresponds to 41\textsubscript{rel} etc. until residue 57\textsubscript{abs}/73\textsubscript{rel} (range |41-73|).
+% \item Residue 40\textsubscript{rel} is missing -- no residue in KLK2 is equivalent to residue 40 in chymotrypsinogen.
+% \item An insertion of 11 amino acids follows residue 95\textsubscript{rel}. These residues are numbered from 95A\textsubscript{rel} to 95K\textsubscript{rel}. Note that both |95A-K| and |95A-95K| are valid ranges.
+% \item The number of the last residue is 245A\textsubscript{rel}(range |245A|).

To this end, each \opt{enlarge ...} key enlarges the bounding box at the respective side (Example~\ref{exa:DomEnlargeBB}).

+% \section{Feature Styles and Shapes}
+% \label{sec:DomFeatureStylesAndShapes}
+%
+% Each (implicit and explicit) feature of a domain chart has a certain \textit{shape} and \textit{style}. For instance, you can see five different feature \textit{shapes} in Example~\ref{exa:DomTikzpicture}: We explicitly added two features of shape (and type) \texttt{disulfide} and three features of shape \texttt{domain}. Furthermore, the package implicitly included features of shape \texttt{other/name}, \texttt{other/main chain} and \texttt{other/ruler}.
+%
+% Although the three \texttt{domain} features agree in shape, they differ in color, or (more generally) \textit{style}. Since \pkg{pgfmolbio} distinguishes between shapes and styles, you may draw equally shaped features with different colors, strokes, shadings etc.
+%
+% \DescribeMacro\setfeaturestyle{<type>}{<style list>}
+% Specifies a \meta{style list} for the given feature \meta{type}. The complete syntax ist
+%
+% \begin{quote}
+% \meta{style list} := \MacroArgs{<style list item>[','<style list item>', ...']}\\
+% \meta{style list item} := \MacroArgs<multiplier><style>\\
+% \meta{multiplier} := \MacroArgs['*'<number>]\\
+% \meta{style} := \MacroArgs<single key-value pair>' | '{<key-value list>}
+% \end{quote}
+%
+% A style list item of the general form |*|\meta{n}|{|\meta{style}|}| instructs the package to repeat the \meta{style} \meta{n}-times. (This syntax is reminiscent of column specifications in a |tabular| environment. However, do \textit{not} enclose numbers with more than one digit in curly braces!) You may omit the trivial multiplier |*1|, but never forget the curly braces surrounding a \meta{style} that contains two or more key-value pairs. Furthermore, \pkg{pgfmolbio} loops over the style list until all features have been drawn.
+%
+% For instance, the style list in Example~\ref{exa:DomFeatureStyle} fills the first feature red, then draws a green one with a thick stroke, and finally draws two dashed blue features.

+% Several commands that are only available in the \meta{TikZ code} allow you to design generic feature shapes:
+% \begin{itemize}
+% \item |\xLeft|, |\xMid| and |\xRight| expand to the left, middle and right $x$-coordinate of the feature. The coordinates are in a format suitable for |\draw| and similar commands.
+% \item |\yMid| expands to the $y$-coordinate of the feature, i.\,e. the $y$-coordinate of the current line.
+% \item You can access any values stored in the package’s \meta{key}s with the macro |\pmbdomvalueof{|\meta{key}|}|.
+% \item The style key \opt{/pgfmolbio/domains/current style} represents the current feature style selected from the associated style list.
+% \end{itemize}
+% The commands above are available for all features. By contrast, the following macros are limited to certain feature types:
+% \begin{itemize}
+% \item |\featureSequence| provides the amino acid sequence of the current feature. This macro is only available for explicitly added features and for \texttt{other/main chain}.
+% \item |\residueNumber| equals the current residue number. This macro is only available for shape \texttt{other/ruler} (see section~\ref{sec:DomRuler}).
+% \item |\currentResidue| expands to a single letter amino acid abbreviation. This macro is only available for shape \texttt{other/sequence} (see section~\ref{sec:DomSequences}).
+% \end{itemize}
+%
+% In Example~\ref{exa:DomFeatureShape1}, we develop a simple \texttt{domain} shape, which is a rectangle containing a centered label with the feature description. Example~\ref{exa:DomFeatureShape2} calculates an additional coordinate for a pentagonal domain shape and stores this coordinate in |\middlecorners|. Note that you have to insert ``pt'' after |\middlecorners| when using the stored coordinate. The domains in Example~\ref{exa:DomFeatureShape3} display a custom shading and inherit their style from the style list.
+%
+% \DescribeMacro\setfeatureshapealias{<new type>}{<existing type>}
+% After calling this macro, the \meta{new type} and \meta{existing type} share a common shape, while they still differ in their styles.
+%
+% \DescribeMacro\setfeaturealias{<new type>}{<existing type>}
+% This is a shorthand for calling both |\setfeatureshape| and |\setfeaturestyle|.

The following auxiliary commands are available for the feature style \TikZ\ code: |\xMid|, |\yMid|, |\residueNumber| and \opt{current style}.
+%

+% \Macro\setfeatureprintfunction{<key list>}{<Lua function>}
+% \Macro\removefeatureprintfunction{<key list>}
+% \Macro\pmbdomdrawfeature{<type>}
+% \end{DescribeMacros}
+% Some features require sophisticated coordinate calculations. Hence, you might ocasionally want to call a Lua function as ``preprocessor'' before executing the \meta{TikZ code} of |\setfeatureshape|. For this purpose, |\setfeatureprintfunction| registers such a \meta{Lua function} and |\removefeatureprintfunction| deletes the preprocessing function(s) for all features in the \meta{key list}.
+%
+% A suitable Lua function
+% \begin{itemize}
+% \item receives up to six arguments in the following order (see also section~\ref{ssc:DocDomLuaPrintFunctions}):
+% \begin{enumerate}
+% \item A table describing the feature (see section~\ref{ssc:DocDomLuaProteinClass} for its fields);
+% \item the left $x$-coordinate of the feature (an integer);
+% \item its right $x$-coordinate (an integer);
+% \item the $y$-coordinate of the current line (an integer);
+% \item the dimension stored in \opt{x unit}, converted to scaled points (an integer);
+% \item the dimension stored in \opt{y unit}, converted to scaled points (an integer);
+% \end{enumerate}
+% \item performs all necessary calculations and defines all \TeX\ macros required by |\setfeatureshape|;
+% \item may execute |\pmbdomdrawfeature| with the appropriate feature \meta{type} to draw the feature.
+% \end{itemize}
+%
+%
+% Example~\ref{exa:DomPrintFunction} devises a new print function, §printFunnySequence§ (lines 2--17). It is similar to the default print function for \texttt{other/sequence} features, but adds random values to the $y$-coordinate of the individual letters.
+%
+% §printFunnySequence§ is a function with six arguments (line 2). We add the width of half a residue to the left $x$-coordinate, §xLeft§ (line 3), since each letter should be horizontally centered. We iterate over each letter in the §sequence§ field of the §feature§ table (lines 4--16). In each loop, calculated coordinates are stored in the \TeX\ macros |\xMid| (lines 5--7) and |\yMid| (lines 8--10). The construction |\string\\...| is expanded to |\\...| when §tex.sprint§ passes its argument back to \TeX. §pgfmolbio.dimToString§ converts a number representing a dimension in scaled points to a string (e.\,g., 65536 to ``1pt'', see section~\ref{sec:DocPkgLua}). The letter of the current residue is stored in |\currentResidue| (lines 11--13). Finally, each letter is drawn by calling |\pmbdomdrawfeature{other/sequence}| (line 14), and the $x$-coordinate increases by one (line 15). Line 25 registers §printFunnySequence§ for \texttt{other/sequence} features.

+% Secondary structures appear along a thin line \meta{factor} times the value of \opt{y unit} above the main chain. In accordance with the categories established by the Dictionary of Protein Secondary Structure\footnote{Kabsch, W. and Sander, C. (1983). Dictionary of protein secondary structure: pattern recognition of hydrogen-bonded and geometrical features. \textit{Biopolymers} \textbf{22}(12), 2577--2637.}, \pkg{pgfmolbio} provides seven features for displaying secondary structure types (Example~\ref{exa:DomShowSecStructure}):

+% \bigskip While changing the appearance of nonhelical secondary structure elements is simple, the complex helical features employ the print function §printHelixFeature§ (section~\ref{ssc:DocDomLuaPrintFunctions}). However, their appearance can be customized on several levels:
+% \begin{enumerate}
+% \item The elements of a helical feature are drawn by five ``subfeatures'', which are called by §printHelixFeature§ (Table~\ref{tab:DomHelixHelperFeatures}a).
+% \item For each subfeature, there is a corresponding shading (Table~\ref{tab:DomHelixHelperFeatures}b; see section~\ref{ssc:DocDomTexSecondaryStructure} and section~83 of the \TikZ\ manual for their definitions).
+% \item These shadings use six colors in total, three for front and three for back shadings (Figure~\ref{fig:DomHelixColors}). For each color, there is a key of the same name, so you can change helix colors in feature style lists (Example~\ref{exa:DomHelixColors}).

+% Note that in Example~\ref{exa:DomInputExternalFiles}, we had to set a sequence length for the |pmbdomains| environment that contains the |\inputgff| macro. \file{gff} files lack a sequence length field. By contrast, \pkg{pgfmolbio} reads the sequence length from an Uniprot file, and thus the mandatory argument of |pmbdomains| may remain empty. In general, the sequence length is stored in the key of the same name.

+% \label{cha:Convert}
+%
+%
+% \section{Overview}
+% \label{sec:ConOverview}
+%
+% The \module{convert} module supports users who wish to include \pkg{pgfmolbio} graphs, but who do not want to typeset their documents with a \TeX\ engine that implements Lua. To this end, the \module{convert} workflow comprises two steps: (1) Running Lua\LaTeX\ on an input file that contains at least one |\pmbchromatogram| or similar macros/environments. This will generate one \file{tex} file per graph macro/environment that contains only \TikZ\ commands. (2) Including this file in another \TeX\ document (via |\input|) which is then processed by any \TeX\ engine that supports \TikZ.
+%
+%
+% \section{Converting Chromatograms}
+% \label{sec:ConChromatograms}
%
+% In order to create the external \TikZ\ file, run an input file like the one below through Lua\LaTeX:
+% \begin{lstlisting}[style=latex-expl,gobble=2]
+% \documentclass{article}
+% \usepackage[chromatogram,convert]{pgfmolbio}
+%
+% \begin{document}
+% \pmbchromatogram[sample range=base 50-base 60]{SampleScf.scf}
+% \pmbchromatogram[/pgfmolbio/convert/output file name=mytikzfile]%
+% {SampleScf.scf}
+% \pmbchromatogram[sample range=base 60-base 70]{SampleScf.scf}
+% \end{document}
+% \end{lstlisting}
+% The \module{convert} module disables \file{pdf} output and introduces the following keys:
+%
+% \DescribeOption{convert/}{output file name}{(auto)}<text>\relax
+% \DescribeOption{convert/}{output file extension}{tex}<text>\relax
+% With the default value for \opt{output file name} (``|(auto)|''), \pkg{pgfmolbio} creates files that are named \file{pmbconverted} and numbered consecutively (\file{pmbconverted0.tex}, \file{pmbconverted1.tex} etc.). Both keys can be changed locally (e.\,g., in the optional argument of |\pmbchromatogram|), but this turns off automatic numbering.
+%
+% The code above produces the files \file{pmbconverted0.tex}, \file{mytikzfile.tex} and \file{pmbconverted2.tex}. Below is an annotated excerpt from \file{pmbconverted0.tex}:
+% \begin{lstlisting}[style=latex-expl,gobble=2,escapeinside=`',basicstyle=\ttfamily\scriptsize,breaklines]

+%
+% You can change the format of the coordinates by the following keys:
+%
+% \DescribeOption{}{coordinate unit}{mm}<unit>
+% \DescribeOption{}{coordinate format string}{\%s\%s}<format string>\relax
+% \pkg{pgfmolbio} internally calculates dimensions in scaled points, but usually converts them before returning them to \TeX. To this end, it selects the \meta{unit} stored in \opt{coordinate unit} (any of the standard \TeX\ units of measurement: \texttt{bp}, \texttt{cc}, \texttt{cm}, \texttt{dd}, \texttt{in}, \texttt{mm}, \texttt{pc}, \texttt{pt} or \texttt{sp}). In addition, the package formats the dimension according to the \meta{format string} given by \opt{coordinate format string}. This string basically follows the syntax of C's \texttt{printf} function, as described in the Lua reference manual.
+%
+% Depending on the values of \opt{coordinate unit} and \opt{coordinate format string}, dimensions will be printed in different ways (Table~\ref{tab:CoordFormat}).
+%
+% \begin{table}

+% \section{Converting Domain Diagrams}
+% \label{sec:ConDomains}
+%
+% \DescribeOption{convert/}{output code}{tikz}'pgfmolbio | tikz'
+% In principle, domain diagrams are converted like sequencing chromatograms (section~\ref{sec:ConChromatograms}). However, \opt{output code} lets you choose the kind of code \module{convert} writes to the output file: |pgfmolbio| generates a |pmbdomains| environment containing |\addfeature| commands, |tikz| produces \TikZ\ code.
+%
+% ``Converting'' one |pmbdomains| environment in the input file to another one in the output file might seem pointless. Nonetheless, this conversion mechanism can be highly useful for extracting features from a Uniprot or \file{gff} file. For example, consider the following input file:
+% \begin{lstlisting}[style=latex-expl,gobble=2]
+% \documentclass{article}
+% \usepackage[domains,convert]{pgfmolbio}
+%
+% \begin{document}
+% \pgfmolbioset[convert]{output code=pgfmolbio}
+% \begin{pmbdomains}{}
+% \inputuniprot{SampleUniprot.txt}
+% \end{pmbdomains}
+% \end{document}
+% \end{lstlisting}
+% The corresponding output is
+% \begin{lstlisting}[style=latex-expl,gobble=2,escapeinside=`']
+% \begin{pmbdomains}
+% [name={TestProtein},
+% sequence=MGSKRSVPSRHRSL`[...]'PLATPGNVSIECP]{200}
+% \addfeature[description={Disulfide 1}]{DISULFID}{5}{45}
+% \addfeature[description={Disulfide 2}]{DISULFID}{30}{122}
+% \addfeature[description={Disulfide 3}]{DISULFID}{51}{99}
+% \addfeature[description={Domain 1}]{DOMAIN}{10}{40}
+% \addfeature[description={Domain 2}]{DOMAIN}{60}{120}
+% \addfeature[description={Domain 3}]{DOMAIN}{135}{178}
+% \addfeature[description={Strand 1}]{STRAND}{15}{23}
+% \addfeature[description={Strand 2}]{STRAND}{25}{32}
+% \addfeature[description={Helix 1}]{HELIX}{60}{75}
+% \addfeature[description={Helix 2}]{HELIX}{80}{108}
+% \addfeature[description={Sugar 1}]{CARBOHYD}{151}{151}
+% \addfeature[description={Sugar 2}]{CARBOHYD}{183}{183}
+% \end{pmbdomains}
+% \end{lstlisting}
+% Obviously, this method is particularly suitable for Uniprot files containing many features.
+%
+% \DescribeOption{convert/}{include description}{true}<boolean>
+% Decides whether the feature description obtained from the input should appear in the output. Since the description field in FT entries of Uniprot files can be quite long, you may not wish to show it in the output. For example, the output of the example above with \opt{include description}|=false| looks like
+% \begin{lstlisting}[style=latex-expl,gobble=2,escapeinside=`']
+% \begin{pmbdomains}
+% [name={TestProtein},
+% sequence=MGSKRSVPSRHRSL`[...]'PLATPGNVSIECP]{200}
+% \addfeature{DISULFID}{5}{45}
+% \addfeature{DISULFID}{30}{122}
+% \addfeature{DISULFID}{51}{99}
+% `[...]'
+% \end{pmbdomains}
+% \end{lstlisting}
+%

% \begin{itemize}
% \item §ALL_BASES§: A table of four indexed string fields, which represent the nucleotide single-letter abbreviations.
-% \item §PGFKEYS_PATH§: A string that contains the \pkg{pgfkeys} path for \opt{chromatogram} keys.
-% \item §header§: A table of 14 named number fields that save the information in the \file{scf} header (see section~\ref{ssc:evaluateScfFile}).
-% \item §samples§: A table of four named subtables §A§, §C§, §G§, §T§. Each subtable contains §header.samplesNumber§ indexed number fields that represent the fluorescence intensities along a trace.
-% \item §peaks§: A table of §header.basesNumber§ indexed subtables which in turn contain three named fields:
-% \begin{itemize}
-% \item §offset§: A number indicating the offset of the current peak.
-% \item §prob§: A table of four named number fields §A§, §C§, §G§, §T§. These numbers store the probability that the current peak is one of the four bases.
-% \item §base§: A string that states the base represented by the current peak.
-% \end{itemize}
-% \item §parms§: A table of 25 named fields that comprise the parameters of the chromatogram. Most of the fields correspond to a key from the \opt{chromatogram} module. For a detailed description, see section~\ref{ssc:setParameters}.
-% \item §selectedPeaks§: A table of zero to §header.basesNumber§ indexed subtables (section~\ref{ssc:printTikzChromatogram} explains how the exact number is determined). This variable is similar to §peaks§, but it only describes the peaks in the displayed part of the chromatogram, which is selected by the |samples range| key (hence the name). Each subtable of §selectedPeaks§ consists of the following five named fields:
-% \begin{itemize}
-% \item §offset§: A number indicating the offset of the current peak in ``transformed'' coordinates (i.\,e., the $x$-coordinate of the first sample point shown equals 1).
-% \item §base§: See §peaks.base§ above.
-% \item §prob§: See §peaks.prob§ above.
-% \item §baseIndex§: A number that stores the index of the current peak. The first detected peak in the chromatogram has index~1.
-% \item §probXRight§: A number corresponding to the right $x$-coordinate of the probability indicator.
-% \end{itemize}
-% \item §lastScfFile§: A string that equals the name of the last \file{scf} file loaded.
+% \item §PGFKEYS_PATH§: A string that contains the \pkg{pgfkeys} path for \module{chromatogram} keys.

+% \subsection{The \texorpdfstring{\texttt{SpecialKeys}}{SpecialKeys} Class}
+% \label{ssc:DocDomLuaSpecialKeysClass}
+%
+% The §SpecialKeys§ class contains three member variables: §disulfideKeys§ (a list of keys that indicate disulfide-like features, like \texttt{disulfide}), §featureStyles§ (a list of feature styles) and §printFunctions§ (a list of keys associated with a feature print function, like \texttt{alpha helix}). Furthermore, it provides methods to manipulate these fields.
+%
+% The constructor §SpecialKeys:new§ generates a new §SpecialKeys§ object and initializes it with values from §parms§.
+% \begin{macrocode}

+ end
+ end
+
+ setmetatable(newSpecialKeys, self)
+ self.__index = self
+ return newSpecialKeys
+end
+
+% \end{macrocode}
+% §SpecialKeys:setKeys§ sets a §value§ for a §key§ in the §keylist§. Possible values for §keyList§ are §"disulfideKeys"§, §"featureStyles"§ or §"printFunctions"§.
+% \begin{macrocode}
+function SpecialKeys:setKeys(keylist, keys, value)
+ for key in keys:gmatch("([^,]+)") do
+ key = key:trim()
+ self[keylist][key] = value
+ end
+end
+
+% \end{macrocode}
+%
+% §SpecialKeys:setFeatureStyle§ parses the style list §style§ and associates it with a certain §key§. In Lua, a style list is an array of tables. Each table contains the fields §cycles§ and §style§. §cycles§ determines how often the §style§ (a string suitable for the mandatory argument of |\pgfmolbioset|) is to be used. In addition, an optional field §alias§ contains a reference to another key, if the current key is an alias of it (see below).
+% \begin{macrocode}
+function SpecialKeys:setFeatureStyle(key, style)
+ local newStyleList, styleCycles, styleContents
+
+ newStyleList = {}

+ )
+ end
+ end
+ self.featureStyles[key] = newStyleList
+end
+
+% \end{macrocode}
+% §SpecialKeys:aliasFeatureStyle§ sets the §alias§ field of a style list so that feature §newKey§ uses the same feature style as feature §oldKey§.
+% \begin{macrocode}
+function SpecialKeys:aliasFeatureStyle(newKey, oldKey)
+ self.featureStyles[newKey] = {alias = oldKey}
+end
+
+% \end{macrocode}
+% §SpecialKeys:getBaseKey§ returns either the name of §key§ itself or of its parent key if §key§ is an alias.
+% \begin{macrocode}
+function SpecialKeys:getBaseKey(key)
+ if self.featureStyles[key] then
+ if self.featureStyles[key].alias then
+ return self.featureStyles[key].alias
+ end
+ end

+% §SpecialKeys:clearKeys§ clears a §keylist§.
+% \begin{macrocode}
+function SpecialKeys:clearKeys(keylist)
+ self[keylist] = {}
+end
+
+% \end{macrocode}
+% §SpecialKeys:selectStyleFromList§ returns the §styleID§-th style from the style list associated with §key§. Firstly, the correct style list is selected.
+% \begin{macrocode}
+function SpecialKeys:selectStyleFromList(key, styleID)
+ local styleList
+
+ if not self.featureStyles[key] then
+ packageWarning(
+ "Feature style `" ..
+ key ..
+ "' unknown, using `default'."
+ )
+ styleList = self.featureStyles.default
+ elseif self.featureStyles[key].alias then
+ styleList = self.featureStyles[self.featureStyles[key].alias]
+ else
+ styleList = self.featureStyles[key]
+ end
+
+% \end{macrocode}
+% Secondly, the method choses the appropriate style in the list.
+% \begin{macrocode}
+ while true do
+ for _, v in ipairs(styleList) do
+ styleID = styleID - v.cycles
+ if styleID < 1 then
+ return v.style
+ end
+ end
+ end
+end
+
+% \end{macrocode}
+%
+% \subsection{The \texorpdfstring{\texttt{Protein}}{Protein} Class}
+% \label{ssc:DocDomLuaProteinClass}
+%
+% The §Protein§ class represents a domain diagram in Lua. Its member variables largely correspond to the keys of the \module{domains} module. In detail:
+% \begin{itemize}
+% \item §sequenceLength§: A value of §-1§ indicates that the sequence length has not been properly set.
+% \item §ft§ is the feature table, i.\,e. an array of tables with the following fields:
+% \begin{itemize}
+% \item §key§: A string that equals the feature key.
+% \item §start§: The start \dots
+% \item §stop§: \dots\ and the end residue of the feature, both in \textit{absolute} numbering. (For the difference between absolute and relative numbering, see section~\ref{sec:DomGeneralLayout}.)
+% \item §kvList§: A string containing comma-separated key-value pairs, which is passed to |\pgfmolbioset| immediately before the feature is drawn.
+% \item §level§: The level of the feature (only relevant for disulfide-like features).
+% \end{itemize}
+% \item §residueNumbering§: An array of strings. The indices are absolute residue numbers, while the fields represent the corresponding relative residue numbers.
+% \item §revResidueNumbering§: The inverse of §residueNumbering§ (i.\,e., a table of numbers).
+% \item §rulerRange§: An array of tables. Each table represents one mark of the ruler and has the fields §pos§ (position in absolute residue numbers) and §number§ (relative number of the marked residue).
+% \item §currentStyle§: A table whose field names equal feature keys. Each field denotes the index of the style that was last selected from that feature's style list.
+% \item §includeDescription§: This boolean field remains uninitialized. Instead, it is directly set in \file{pgfmolbio.domains.tex} if the \module{convert} module is loaded and the user requests a string representation of a §Protein§ object (section~\ref{ssc:DocDomLuaTostring}).
+% \end{itemize}
+%
+% The constructor §Protein:new§ initializes the member variables with default values.

+% \subsection{Uniprot and GFF Files}
+% \label{ssc:DocDomLuaReadFiles}
+%
+% §Protein:readUniprotFile§ reads the relevant parts of Uniprot file §filename§\footnote{For a detailed description of this format, see \url{http://web.expasy.org/docs/userman.html}.}.
+% \begin{macrocode}
+function Protein:readUniprotFile(filename)
+ local uniprotFile, errorMsg = io.open(filename, "r")
+ if not uniprotFile then packageError(errorMsg) end
+
+% \end{macrocode}
+% Each line in a Uniprot file starts with a line code consisting of two letters. This code determines the syntax of the remainder of the line.
+% \begin{macrocode}
+ local sequence = {}
+ local inSequence = false
+ local featureTable = {}
+
+ for currLine in uniprotFile:lines() do
+ local lineCode = currLine:sub(1, 2)
+ local lineContents = currLine:sub(3)
+% \end{macrocode}
+% The \texttt{ID} line is the first line in a Uniprot file. It provides two relevant properties of the protein, namely its name and ints sequence length. For example, in the file \file{SampleUniprot.txt} (see section~\ref{sec:DomFileInput}), the \texttt{ID} line reads\\
+% |ID TestProtein Reviewed; 200 AA.|\\
+% which declares a protein with 200 residues called TestProtein.

+% \end{macrocode}
+% \texttt{FT} lines describe features of the protein (domains, disulfides, sugars etc.). The first line of a feature always contains its key (columns 6--13) and endpoints (columns 15--20 and 22--27, respectively). The description (columns 35--75) may span several lines, in which case the key columns of consecutive lines are empty. For instance,\\
+% |FT DOMAIN 10 40 Domain 1|\\
+% declares a \texttt{DOMAIN} feature between residues 10 and 40 with description ``Domain 1''.

+ featureTable[#featureTable].description .. description
+ end
+% \end{macrocode}
+% The \texttt{SQ} line starts the sequence block. Each of the following sequence data lines lacks a line code and shows the amino acid sequence in one letter code, e.\,g.\\
+% |SQ SEQUENCE 200 AA; 22041 MW; 00A52FE2EC5431D9 CRC64;|\\
+% | MGSKRSVPSR HRSLTTYEVM FAVLFVILVA LCAGLIAVSW LSIQ| [\dots]

+% The |\\| line terminates the Uniprot file.
+% \begin{macrocode}
+ elseif lineCode == "\\\\" then

+ end
+ end
+% \end{macrocode}
+% After closing the file, features are converted to the proper format (section~\ref{ssc:DocDomLuaProteinClass}).

+% \subsection{Adding Feature}
+% \label{ssc:DocDomLuaAddFeature}
+%
+% §Protein:addFeature§ converts raw feature information to the format of §ft§ fields (described in section~\ref{ssc:DocDomLuaProteinClass}). Firstly, the method determines the index of the style that should be used for the current feature.
+% \begin{macrocode}

+% \subsection{Calculate Disulfide Levels}
+% \label{ssc:DocDomLuaDisulfideLevels}

+% Otherwise, the algorithm looks for the first free level (starting at level 1), i.\,e. the first level the feature may occupy without clashing with another one. (1) If the level currently checked already exists, it has been created by a previous disulfide-like feature.

+% §Protein:__tostring§ is required by the \module{convert} module and returns a |pmbdomains| environment that contains all the information stored in the §Protein§ object (section~\ref{sec:ConDomains}). Firstly, we start the environment.
+% \begin{macrocode}
+function Protein:__tostring()
+ local result = {}
+ local currLine
+
+ currLine = "\\begin{pmbdomains}\n\t\t[name={" ..
+ self.name ..
+ "}"
+ if self.sequence ~= "" then
+ currLine = currLine ..
+ ",\n\t\tsequence=" ..
+ self.sequence
+ end
+ currLine = currLine ..
+ "]{" ..
+ self.sequenceLength ..
+ "}"
+ table.insert(result, currLine)
+
+% \end{macrocode}
+% Afterwards, each feature in the feature table is converted to an |\addfeature| macro. Note the use of the §includeDescription§ field (described in section~\ref{ssc:DocDomLuaProteinClass}).
+% \begin{macrocode}
+ for i, v in ipairs(self.ft) do
+ if v.key ~= "other/main chain" then
+ currLine = "\t\\addfeature"
+ if self.includeDescription and v.description then
+ currLine =
+ currLine ..
+ "[description={" ..
+ v.description ..
+ "}]"
+ end
+ currLine =
+ currLine ..
+ "{" ..
+ v.key ..
+ "}{" ..
+ v.start ..
+ "}{" ..
+ v.stop ..
+ "}"
+ table.insert(result, currLine)
+ end
+ end
+% \end{macrocode}
+% Finally, we close the environment.
+% \begin{macrocode}
+ table.insert(result,
+ "\\end{pmbdomains}"
+ )
+ return table.concat(result, "\n")
+end
+% \end{macrocode}
