[PyMOL] Ligand Surface Representation

[Simon Holton]

Hi Folks,

	I'm trying to generate a surface for a ligand which is part of a  
ligand-protein complex.  I realise this is the other way around to  
normal, but somehow when I select the ligand in pymol and then 'show  
surface, ligand', absolutely nothing happens.  No error, but no  
surface.  The same happens if I just open a pdb file describing the  
ligand alone.  Other representations work, but the problem is not PDB  
specific.  I'm using the macpymol X11 hybrid (0.98)

        Any suggestions?

Cheers
