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.

Spotlight

VMD includes a Ramachandran plot plugin which plots Phi and Psi angles for a selected molecule. The angle plot automatically updates when simulation trajectory frames are advanced by hand, or when animated. Each plotted angle is individually selectable, and reports its segment ID, residue name, residue ID, Phi angle, and Psi angle, when selected. Ramachandran plots can be saved to a postscript file for inclusion into publications.
