[gmx-users] spatial restraints

[Stefano Guglielmo]

Hello gromacs users,

I would like to know if it is possible to add spatial restraints to a
selected subgroup of atoms of my system (protein+membrane+ligand+water)
without generating a new topology: I have a top generated with parmed fed
with the suitable amber ff and I would like just to add the atoms that
should be restrained to the existing topology.
Thanks in advance
Stefano
