The problem seems to be between 3 S of CYS residues. I only use the 20 usual residues and with no modifications.
Where is the ffbonded.itp file? Thank you, Pierre THEVENET ----- Mail original ----- De: "Justin A.

This would be highly unusual for a standard protein. Are you using any custom residues? The error message indicates the line in the .top that is causing the problem. Look it up, find which atoms it corresponds to, and check ffbonded.itp to verify that suitable parameters are indeed not present. If you're using some kind of custom residue or nonstandard composition of atoms, then you'll likely have to parameterize the missing term(s) yourself. -Justin -- ======================================== Justin A.
