mol2ps is a freely available command-line utility program which reads molecular structure files in different formats (see below) and generates Postscript output for 2D display. The Postscript file can then be used e.g. for creating a bitmap file, using a Postscript interpreter like
Ghostscript.
As an example, the following 2D representation of caffeine in PNG (Portable Network Graphics) format was created from the corresponding MDL molfile (
PubChem CID
2519), using mol2ps in combination with Ghostscript:
As input files, MDL molfiles and SD files (*.mol, *.sdf; 2D and 3D), Alchemy molfiles (*.mol), and Sybyl mol2 files (*.mol2) are accepted by mol2ps, the preferred format is the MDL molfile format. At present, it is not intended to extend the number of supported input file formats, as there are powerful file format converters available, such as
OpenBabel.
The main purpose of mol2ps is to create small, but high-quality 2D pictures of molecules for display on web pages. Especially for web-based molecular structure databases it is quite useful to have pre-built pictures for display in hitlists instead of invoking browser plugins,
Java applets, or server-side programs for display of the individual structures. A description of how such structure databases can be created with free software is given
here.
