I have added 1.AMBER14SB_parmbsc1
2: AMBER99 force field BSC1
in my working directory but it still gives the error-
Residue 1 named DG of a molecule in the input file was mapped
to an entry in the topology database, but the atom C5' used in
that entry is not found in the input file. Perhaps your atom
and/or residue naming needs to be fixed.
I have given command to change clean.pdb file to processed.gro file but it still gives the error .
