PyMOL is open-source, user-sponsored, molecular graphics system with an embedded Python interpreter designed for real-time visualization and rapid generation of high-quality molecular graphics images and animations. PyMOL is scriptable and can be extended using the Python language. PyMOL is an active project, and there are new features being added to it frequently. open in new windowPyMOL web site Home page.

Last update: 8 June 2010, Version 1.3
Platforms: Windows, Mac OSX, Unix, Linux
Access to precompiled PyMOL buildsis now limited to paying customers only. However, the current source code continues to be available at no cost as are older precompiled builds. Precompiled PyMOL builds available at no cost also to teachers or full-time students upon registration.
Development: DeLano Scientific LLC
Plugins Plugins are user-developed modules that extend PyMOL's capabilities. In order to use the plugins, you'll need an Tcl/Tk-based version of PyMOL (on Macs, this means either the Fink or X11/Hybrid versions ). For installation instruction see PyMOL manual.
