PyMOL is a powerful and comprehensive molecular visualization product for rendering and animating 3D molecular structures. It is a user-sponsored molecular visualization system on an open-source foundation.
Citation:
There are no peer reviewed publications on PyMOL yet. So, if your journal is hip enough to allow URL citations, please cite PyMOL as:
The PyMOL Molecular Graphics System, Version 1.2r3pre, Schrödinger, LLC.
You get the idea…and please don’t forget to send PyMOL the reference for your article when it comes out so that I can add it to the list of publications which used PyMOL.
