=head1 DESCRIPTION

Generate HTML file(s) from I<SDFile(s)>. The HTML file(s) contain data tables
and appropriate navigational links to view other tables; navigational links are also
provided on compound HTML pages. These files can be generated for local viewing or
deployment on a web server. A variety of options are provided to control style and
appearance of tables. And for viewing structures, options are available to use any one of
these viewers: Chem3DActiveX, ChemDrawActiveX, ChemDrawPlugIn, Chime, Jmol, JME,
MarvinView, or ViewerActiveX. Jmol is the default structure viewer and it is also distributed
along with this package; however, to use any other supported viewers, make sure it's available
in your environment.

Multiple I<SDFile(s)> names are separated by space. The valid file extensions are
I<.sdf> and I<.sd>. All other file names are ignored. All the SD files in a current directory can
be specified either by I<*.sdf> or the current directory name.

B<--cmpddatafield> option value is also linked to compound summary page.

=item B<--datafields> I<"fieldlabel,[fieldlabel]..." | Common | All>

Data fields to display in HTML table(s). Possible values: list of comma separated data field
labels, data fields common to all records, or all data fields. Default value: I<All>.
Examples:

    ALogP,MolWeight,EC50
    "MolWeight,PSA"

=item B<--footer> I<string>

Text string to be included at bottom of each HTML file. Default: none.

=item B<-d --displaylinks> I<top | bottom | both>

Specify where to display navigation links in each HTML file for accessing all other HTML
files. Possible values: I<top, bottom, or both>. Default: I<both>. This option is
only valid during multiple HTML files generation for an input file.

=item B<--displaylinksinfo> I<compound | table | both>

Control display of additional information along with navigational links: Showing compound
n of m is displyed for compound and showing table n of m for table. Possible values: I<compound
| table | both>. Default: I<both>. This option is only valid  during multiple HTML files generation.

=item B<-h, --help>

Print this help message.

=item B<--headeralign> I<left | center | right,[top | middle | bottom>

Horizontal and vertical alignment for table header rows. Possible horizontal alignment
values: I<left, center, or right>. Possible vertical alignment values: I<top, middle, or bottom>.

Default values: I<center,middle>

=item B<--headercolor> I<#RRGGBB>

Color used to fill background of table header row containing column labels
represented as a hexadecimal string. Default value: None for B<-m, --mode> option
value of I<plain> and I<#ccccff>, light blue, for others.

=item B<--highlight> I<"fieldlabel,datatype,criterion,value,[fieldlabel,datatype,criterion,value,...]">

Highlighting methodology used to highlight various SDFile(s) data field values in
HTML file(s). Same set of quartets values are applied to all SDFile(s).

Input text contains these quartets: I<fieldlabel,datatype,criterion,value,...>.
Possible datatype values: I<numeric or text>. Possible criterion values: I<le, ge, or eq>.
Examples:

    "MolWt,numeric,le,450"
    "MolWt,numeric,le,450,LogP,numeric,le,5"
    Name,text,eq,Aspirin

=item B<--highlightcolor> I<"#RRGGBB,#RRGGBB">

Colors used to highlight column values during I<highlight> and I<shadedhightlight>
mode represented as hexadecimal strings.

For B<--highlighstyle> option values of I<text> and I<background>, these colors represent
text or background colors respectively. For a specific column, first color string is used for
values which meet criterion indicated by B<--highlight> option; the second color is used for
 rest of the values.

Default values for I<background> B<--highlightstyle>: I<"#0fff0f,#ff0f0f">. And default values for
I<text> B<--highlightstyle>: I<"#0fbb0f,#ff0f0f">. Hexadecimal strings for both B<--highlightstyle>
colors correspond to I<reddish> and I<greenish>.

=item B<--highlightstyle> I<text | background>

This value is mode specific. It indicates highlight style used to differentiate column
values which meet a specified criterion in B<--highlight> option. Possible values: I<text or
background>. Default: I<background>.

=item B<-m, --mode> I<plain | shade | highlight | shadedhighlight | structuresonly | shadedstructuresonly>

Specify how to generate HTML table(s): plain tables with line borders, background of
alternate rows filled with a specified color, column values highlighted using a specified
criteria, combination of previous two styles,  tables containing only structures, or tables
containing only structures with filled background of alternate rows.

Possible values: I<plain, shade, highlight, shadedhighlight, structuresonly, or
shadedstructuresonly>. Default: I<shade>.

=item B<-n, --numcmpds> I<number>

Maximum number of compounds per table. Default value: I<15> for tables with structures and
I<50> for tables with links to structures. Use 0 to put all compounds into one table. For SDFile(s)
with more than maximum number of specified compounds, multiple HTML tables, with appropriate
navigation links, are created.

=item B<-o, --overwrite>

Overwrite existing files.

=item B<-r, --root> I<rootname>

New file or directory name is generated using the root: <root>.html or <root>-html.
Default new file name: <InitialSDFileName>.html. Default directory name:
<InitialSDFileName>-html.

For SDFile(s) with more than maximum number of specified compounds per table,
this directory tree is generated using <Name> where <Name> corresponds to <root>
or <InitialSDFileName>: Top dir - <Name>-html; Sub dirs - html and mols. <Top dir> contains
<Name>.html and <Name>.css files and <sub dir> html conatins various
<Name>Lines<Start>To<End>.html files; <sub dir> mols is created as needed and contains
MOL files.

This option is ignored for multiple input files.

=item B<-s, --structure> I<display | link>

Structure display control: display structures in a table column or set up a link for each
structure which opens up a new HTML page containing structure and other appropriate
information. Possible values: I<display or link>. Default value: I<display>

The default viewer, JmolApplet V10, is distributed with MayaChemTools package.
Earlier versions of JmolApplet are not supported: due to applet security issues related to
reading files, this script uses in-line loading of MOL files and this option doesn't exist in
earlier version of JmolApplet.

=item B<--strviewerconfig> I<codebase[,archive,code]>

Configuration information for structure viewers. This option is only valid for structure
viewers which are applets: Jmol, JME and MarvinView. For other viewer types available via
B<--strviewertype> option  - MDL Chime, ChemDrawActiveX, ChemDrawPlugIn, and
Chem3DActiveX - this value is ignored.

Input text format: I<codebase[,archive,code]>. For an applet viewer, I<codebase> must be
specified; I<archive> and I<code> values are optional. Here are default I<archive> and
I<codebase> values for various applets: Jmol - JmolApplet, JmolApplet.jar; JME - JME, JME.jar;
 MarvinView: MView, marvin.jar

For local deployment of HTML files, I<codebase> must correspond to a complete path to
the local directory containing appropriate I<archive> file and the complete path is converted
into appropriate relative path during generation of HTML files.

By default, I<codebase> value of <this script dir>/../lib/Jmol is used for I<Jmol> applet viewer, and
HTML file(s) are generated for local deployment; however, you can specify any supported
applet viewer and generate HTML file(s) for deploying on a web server.

For deploying the HTML file(s) on a web server, specify a valid I<codebase> directory name
relative to <WWWRootDir>. Example when JME archive file, JME.jar, is available in
I</jme> directory on the web server:

    /jme

For local deployment of HTML file(s), specify a complete I<codebase> directory name.
Example when JmolApplet archive file, JmolApplet.jar, is present in <JMOLROOT> directory:

    <JMOLROOT>

In addition to I<codebase>, you can also specify I<archive> file name. Example for web
deployment:

    "/jme,JME.jar"
    "/jme"

Example for local deployment:

    "<JMEROOT>,JME.jar"
    "<JMEROOT>"

=item B<--strviewerparams> I<"name=value [name=value ...]">

Parameters name and value pairs for structure viewers. These name and value pairs
are used to control the appearance and behavior of structure viewers in tables and
compound HTML page during I<link> value for B<-s --structure> option.

The parameter names, along with their values,  are just passed to each structure viewer
in appropriate format without checking their validity. Check documentation of appropriate
structure viewers to figure out valid parameter names.

Input text format: I<name=value name=value ...> Example:

    "width=250 height=170"

Default for all structure viewers: I<width=250 height=170> for displaying structures in
tables, and I<strlinkwidth=500 strlinkheight=295> for compound HTML page during I<link> value
for B<-s --structure> option.

Default background color for all structure viewers: same as B<--shadecolor> value for
displaying structures in tables and I<strlinkbgcolor=#ffffff> for  compound HTML page;
however, explicit specification of background color in this option overrides default value.
To use black background for structures in tables and compound HTML page, specify I<bgcolor=#000000>
and I<strlinkbgcolor=#000000> respectively.  Keep this in mind: Some structure viewers
don't appear to support background color parameter.

Additional structure viewer specific default values:

    Chem3DActiveX: "displaytype=Ball&Stick rotationbars=false
                    moviecontroller=false"
    ChemDrawActiveX: "ViewOnly=1 ShrinkToFit=1 ShowToolsWhenVisible=1"
    ChemDrawPlugIn: "type=chemical/x-mdl-molfile ViewOnly=1
                     ShrinkToFit=1 ShowToolsWhenVisible=1"
    Chime: "display2d=true"
    JME: "options=depict"
    Jmol: "progressbar=true progresscolor=#0000ff boxbgcolor=#000000
           boxfgcolor=#ffffff script="select *; set frank off;
           wireframe on; spacefill off""
    MarvinView: "navmode=zoom"
    ViewerActiveX:"Mouse=4 Convert2Dto3D=0"

Try overriding default values or specify additional valid parameter/value pairs to get desired
results. Example for using CPK rendering scheme with Jmol viewer:

    "script="select *; set frank off; wireframe off; spacefill on""

=item B<--strviewerembed> I<direct | javascript>

Specify how to embed structure viewers in HTML pages. Possible values: I<direct> - use applet/object
tags to emded structure viewer; I<javascript> - use vendor supplied java scripts. Default value:
direct.

This option only applies to these vieweres: I<Chem3DActiveX, ChemDrawActiveX, ChemDrawPlugIn,
Jmol, and MarvinView>.

For marvin.js to work correctly on your browser, you may need to set I<marvin_jvm=builtin> or
I<marvin_jvm=plugin> using B<--strviewerparams> option. Additionally, MarvinView - at least
in my hands - also has problems during usage of JavaScript for local deployment; however, it
does work via web server.

As far as I can tell, Jmol.js supplied with Jmol10 release has these issues: jmolSetAppletColor
doesn't support background color; jmolInitialize disables relative specification of codebase
directroy which works okay. So, use Jmol.js supplied with MayaChemTools.

=item B<--strviewerjsfile> I<java script file name>

Name of vendor supplied java script file. Default values: Chem3DActiveX: I<chem3d.js>; ChemDrawActiveX,
and ChemDrawPlugIn: I<chemdraw.js>; Jmol: I<Jmol.js>, MarvinView: I<marvin.js>.

Directory location for these files is specified via I<codebase> value of B<--strviewerconfig> option.

=item B<--strtablesize> I<"numrows,numcols">

This option is only valid for I<structuresonly> and I<shadedstructuresonly> modes. And it indicates
maximum number of rows and columns per structure table. Default value:I<6,4>.

=item B<--stylesheet> I<old | new | none>

Controls usage of stylesheet for newly generated HTML file(s). Possible values: I<old,
new, or none>. Default value: I<new>.

Stylesheet file contains various properties which control appearance of HTML pages:
type, size, and color of fonts; background color; and so on.

For I<old> value, an existing stylesheet file specified by B<--stylesheetname> option is
used for each HTML file; no new stylesheet file is created. This option is quite handy
for deploying HTML file(s) on a web server: assuming you specify a valid stylesheet
file location relative to your WWWRoot, a reference to this stylesheet is added to each
HTML file. For local deployment of HTML file(s), a complete path to a local stylesheet
is fine as well.

For I<create> value, a new stylesheet is created and reference to this local stylesheet
is added to each HTML file. Use option B<--stylesheetname> to specify name.

For I<none> value, stylesheet usage is completely ignored.

=item B<--stylesheetname> I<filename>

Stylesheet file name to be used in conjunction with B<-s --stylesheet> option. It is only
valid for I<old> value of B<-s --stylesheet> option. Specify a valid stylesheet file location
relative to your WWWRoot and a reference to this stylesheet is added to each HTML
file. Example: I<"/stylesheets/MyStyleSheet.css">. Or a complete path name to a local
stylesheet file.

For I<create> value of B<-s --stylesheet> option, a new stylesheet file is created using
B<-r --root> option. And value of B<--stylesheetname> is simply ignored.

=item B<--shadecolor> I<"#RRGGBB,#RRGGBB">

Colors used to fill background of rows during I<shade> and I<shadedhightlight> mode
represented as a pair of hexadecimal string; the first and second color values
are used for odd and even number rows respectively.

Default value: I<"#ffffff,#e0e9eb"> - it's white and very light blue for odd and even number rows.

=item B<-t, --title> I<string>

Title for HTML table(s). Default value: I<SDFileName>. This option is ignored for
multiple input files. And B<-r --root> option is used to generate appropriate
titles.

=item B<--titledisplay> I<yes | no>

Display title for HTML table(s). Possible values: I<yes or no>. Default value: I<yes>.

=item B<-w, --workingdir> I<dirname>

Location of working directory. Default: current directory.

=head1 EXAMPLES

HTML table file(s), containing structures, can be used in two different ways: browsing on a
local machine or deployment via a web server. By default, HTML file(s) are created for viewing
on a local machine using Jmol viewer through a browser; however, you can specify any
supported applet viewer and  generate HTML file(s) for deploying on a web server.

First two sets of examples show generation of HTML file(s) using different applet viewers
and a variety of options for local browsing; last set deals with web deployment.

B<Local deployment: Usage of default JMol viewer distributed with MayaChemTools:>

To generate HTML tables with structure display using JMol viewer, rows background filled
with white and light blue colors, navigation links on top and botton of each page, type:

    % SDFilesToHTML.pl -o Sample1.sdf

To generate HTML tables with structure display using JMol viewer, rows background filled
with white and light blue colors, navigation links on top and botton of each page, and
only containing MolWeight and Mol_ID SD data fields, type:

    % SDFilesToHTML.pl --datafields "MolWeight,Mol_ID" -o Sample1.sdf

To generate HTML tables with CPK structure display using JMol viewer, rows
background filled with white and light blue colors, navigation links on top and botton of
each page, type:

    % SDFilesToHTML.pl --strviewerparams "script=\"select *; set frank off;
      wireframe off; spacefill on\"" -o Sample1.sdf

To generate HTML tables with structure display using JMol viewer and black background, rows
background filled with light golden and greyish colors, navigation links on top and botton of
each page, 10 rows in each table, greyish header row color, and cell spacing of 1, type:

    % SDFilesToHTML.pl -o -n 10 --headeralign "center" --headercolor
      "#a1a1a1" --shadecolor "#fafad2,#d1d1d1" --cellspacing 1
      --strviewerparams "bgcolor=#000000" Sample1.sdf

      path>" -o Sample1.sdf

B<Web deployment: Usage of different structure viewers and options:>

For deploying HTML file(s) on a web server, specify a valid I<codebase> directory name
relative to <WWWRootDir>. In addition to I<codebase>, you can also specify I<archive> file
name.

    % SDFilesToHTML.pl -m plain -s display --strviewertype Jmol
      -strviewerconfig "/jmol" -n 5 -d both -r PlainTable -t "Example
      using Jmol: Plain Table" -o Sample1.sdf
