VAL error

Created by: micmalti

I'm getting this error:

Traceback (most recent call last):
  File "pdb2lmp.py", line 299, in <module>
    conv.collect_types()
  File "pdb2lmp.py", line 99, in collect_types
    dbmol = self.moldb.molecules[mol.name]
KeyError: 'VAL'

I suspect that I should modify the pdb2lmp.py such that it recognizes the .pdb file which I'm trying to convert. Could you kindly tell me what I must do?
