Use "desc lig" to get a description of the ligand (and "desc lig.1", "desc
lig.2", etc. to get residue-specific details).
It looks like you may be getting the wrong residues (i.e. that residue 1
doesn't have C1, and residue 2 doesn't have O). You may also consider
putting a 1 at the end of the bond command as the bond order, but from the
usage statement that appears to be optional.
Hope this helps,
Jason
