matt,
please keep in mind that a 'saved state' .vmd file only contains
the description of the visualization and _not_ the coordinates.
so if you do any manipulation you have to also save the coordinates
(e.g. as described by cesar) and then combine the individual files
into one large file and operate on that file.

especially for large array the scripted translation/rotation of
an atom selection has a lot of appeal.
cheers,
