VMD is a molecular visualisation program for displaying, animating, and analysing large biomolecular systems using 3-D graphics and built-in scripting.

Before you move to the next step, take some time to have a look here on how to use the VMD tool on CSF.

Then, type the following command to launch the application:

qrsh -cwd -V -l short vmd

In the VMD Main window, choose File → New Molecule... Another window, the Molecule File Browser window, will appear on your screen. Use the Browse... button to find the traject.vtf in your scratch/DPD/EX1 directory. In order to actually load the file you have to press Load. It will take some time to load all the frames of the trajectory.

If you get an error, go back to the previous link and have a look again!

Visit the website to find more information on how to display your system in various ways using the Graphical Representations option. Spend some time to familiarise with the basic functions of VMD.
