Hello:
  I've got a modified small peptide and I would like to calculate the partial charge for the non-standard group in this derived peptide. For it would be used for MD simulation based on CHARMM FF, so I am wondering how can I calculate partial charge for the non-standard group based on CHARMM principle?

Thank you very much
