Hi denny,
I'm sorry for replying late
The best way to combining them together is Copy and Paste both of them in Text
editor.
you can do the following :
Take the protein pdb and add a TER card on the end. The cat the receptor pdb
file onto the end of the protein one.
I don't know details of your pdb files
would you please send me pdb files to help you better.
hope this helps you
Sajad

and a ligand?
ok, another newbie question.
I can *see* all the residues now, but how do I get VMD to tell me which residues
I'm actually looking at? I'm figuring it must be some command line thing along
the lines of
resid of (my command from below)
thanks!
