PyMOL is a molecular visualization and manipulation system based on an Open-Source software foundation. The program is designed to meet a variety of the molecular graphics, animation, and presentation needs of research scientists in academia and industry, including display of structure information over a LAN or the internet. Here we demonstrate how PyMOL can be used as an interent helper application with the Fedora system, or as a standalone application.

Though most version of PyMOL may be obtained and used without licensing costs, all users are asked to purchase a PyMOL license and annual support subscription so that DeLano Scientific can develop, maintain, and support the package.
