Dear gromacs users,
I am trying to build the topology for a protein-ligands system. When I run
grompp I obtain 96 of the following errors:

ERROR 1 [file topol_Protein_chain_S.itp, line 38658]:
  No default Proper Dih. types

The errors correctly says that dihedral parameters are missing for my
My question is, there is a method to avoid considering such a dihedrals,
avoiding topology editing?
In other words, I don't wanna edit the .top file removing by-hand the lines
generating the error.
