Hi, Use make_ndx you will see the default grouping of atoms. Type 'q' to quit and save the index.ndx.
Those 149 atoms shall be from residue name that is unknown to Gromacs, find it from their index number from index.ndx and add to aminoacid.dat (increment the number on top as well) located at top directory of Gromacs. Besides, coupling ions alone is not encourage. There were too many times mentioning this on the list. Merge them into SOL group.
