[gmx-users] Fatal error: Residue 'IAE' not found in residue topology database

[Vlad Scepanovsky]

   During the conversion of the PDB file i came to such a problem:
just before the end  of conversion the program pdb2gmx.exe told that my
PDB file compound is not included into Gromacs residue topology database.
Directly as it says:
" Fatal error: Residue '....' not found in residue topology database "
  Woud you be so glad to tell me how can I resolve this problem?

                                               Thank you for advice
                                                         Senserely yours Vladimir Schepanovsky.
