Error:
Fatal error:
[ file strong_posre_make_ligand.itp, line 5 ]:
Atom index (4579) in position_restraints out of bounds (1-43).
This probably means that you have inserted topology section "position_restraints"
in a part belonging to a different molecule than you intended to.
In that case move the "position_restraints" section to the right molecule.
