whether GROMACS can do rmsd restrain of a protein it its starting conformation throughout the whole simulation?

Hi all. I have a query. It is about Whether GROMACS can do rmsd restraint of a protein throughout the whole simulation. I found Gromacs can do only position restraint. But my intention is the...
