VMD is a molecular visualization program for displaying, animating, and analyzing large biomolecular systems using 3-D graphics and built-in scripting. VMD supports computers running MacOS-X, Unix, or Windows, is distributed free of charge, and includes source code.
These plugins were developed totally or partially at the department of Physiology and Biophysics at Weill Cornell Medical College.
Many people seem to have problems installing these plugins. To help with this issue I have written a small guide on how to install third party VMD plugins in a central location without modifying the VMD installation.
