atom selection are inherently tied to a single molecule.

this cannot work, because VMD will read the 'structure' only from
the first molecule, and then only read the coordinates, i.e. it will
refuse any second data set that does not have the matching number
of atoms.
what you have to do is to merge the files. what type of files do
you have? is this just pdb files, or .psf/.dcd trajectories, or??
cheers,
axel.
