O X X C 2 0.0000 1004.16 NH1 X X H 2 0.0000 167.36 under [ dihedraltypes ] card in ffbonded.itp file are the improper dihedral parameters for the peptide bonds as defined in aminoacids.rtp file with the following statement: [ impropers ] N -C CA HN C CA +N O If so, why isn't it C X X O if the first atom should be the to which all the others are connected? Best Regards, Dawid PS I have sent the same question to a different address.
