Check the line as specified in the warning. And translate the atom number to its atom type. Check such combination in the [dihedral] section in the ffX-nb.itp whether there is such combination. I suspect that there is some mis-naming by pdb2gmx. Check the total charge of the molecule as

Hi all I have a short question. Could you please tell me what do the columns in pull.pdo (output file from AFM) stand for. Is there a simple way to obtain forces from AFM pulling? Thank you for help. Michal As an example, with one pulling group, and pulling in 3D, the output columns
