Neither of the files contains molecules:
- rec.ms is a dot molecular surface. It might be hard to see if the
dots are very small; if you zoom out it will be more obvious.
- sphere_cluster.pdb just contains the sphere centers in PDB format,
which will look like a bunch of disconnected dots. In the "wire"
representation these may also be hard to see, so you might show them as
"bs" or "sphere" (note that the sphere representation will not show the
sizes computed by sphgen, it will just make them all bigger balls of
All you need to do is open those files with File... Open. I just used
the files downloaded from the DOCK tutorial to test this. If you want
to see the receptor or ligand at the same time, you have to
additionally open those files.
I hope this helps,
