Hi there,

Based on the above statement, it seems that you loaded the structure and
trajectory files as two separate molecules. What you want to do is load the
trajectory such that its frames are "added" to the structure file. The
following
section of the VMD user's guide:

http://www.ks.uiuc.edu/Research/vmd/current/ug/node41.html

should indicate how to do this; the key here is setting the "Load files
for:"
field. The result should be that both files will be loaded into VMD as one
molecule, and not as two separate molecules.

Hope this helps,
Tim
