By default, current versions of PyMOL excludes PDB HETATMs from surface calculations. The idea behind this is to enable you to easily surface the protein away from solvent and ligands. To change this:
set surface_mode=1 which will cause all atoms to be included. Cheers, Warren PS. surface_mode=2 will exclude all atoms but hydrogens. -- mailto:war...@sunesis.com Warren L.

Warren, I'm trying to surface a ligand independently from the protein in which it's embedded to show the binding pocket more clearly. For some reason, pymol will not draw a surface around this particular molecule. It will surface amino acids, but not this retinal. Is there an obvious reason for this? If I type pymol> show surface, (resn ret).. nothing happens... If I abstract the ligand into a separate PDB file, it still doesn't do anything... I'm using v0.78 I'll include the pdb file in question. Bryan
