WARNING: WARNING: Residue 1 named MET of a molecule in the input file was
mapped
to an entry in the topology database, but the atom H used in
an interaction of type angle in that entry is not found in the
input file. Perhaps your atom and/or residue naming needs to be
fixed.



WARNING: WARNING: Residue 318 named ASP of a molecule in the input file was
mapped
to an entry in the topology database, but the atom O used in
an interaction of type angle in that entry is not found in the
input file. Perhaps your atom and/or residue naming needs to be
fixed.
