RE: movie for subset of atoms

You would have to save the entire trajectory in PDB format, but if you
then load it into PyMOL, it can do this on-the-fly with a command like:

show (resi 1:5 or (byres (resn WAT and (resi 1:5 around 6))))

Assuming you want to see waters within 6 A of residues 1:5.

If you trajectory is huge, the it would make sense to first run PyMOL in
batch/command mode in order to generate the subset, and then load the
result into interactive PyMOL.
