VMD (Visual Molecular Dynamics) is a molecular visualization program with 3-D graphics and built-in scripting for displaying, animating, and analyzing large biomolecular systems. It is also an effective front end visualisation and interaction package for simulations running on NAMD.

VMD can be run as either an interactive or batch application.
To run in interactive mode, first request an interactive session on one of the backend compute nodes via the scheduler. If compute facilities are available at the time of your request then a new terminal window will be launched.
qsh -cwd -V -l h_rt=01:00:00
will request an interactive shell with 1 hour of run-time (the -l h_rt parameter). Once in the interactive shell, enter these two commands to
start a graphical session:
module load vmd vmd
After exiting VMD, enter the exit command in the interactive window to close the session.
As VMD has both a GUI and a text interface, scripts can be written to automate functions such as loading molecules, creating representations, making animations and analysing data. These commands can be entered in a batch script and then submitted through the batch queue in the normal way. An example script to create a movie of a molecular representation:
