You pdb file contains non-standard atom names. The carboxylic oxygens
on a C-terminal residue need to be named "O" and "OXT". Edit the pdb file
to change these.

To find this out for yourself, use the "desc" command in tleap to see what
atom names are in the CGLU unit: you pdb file has to match these.
