Hi everyone,
I am doing a simulation of a protein using gromacs with charmm forcefields.
>From the crystallographic analysis, it is found that certain residues are
rigid and few are flexible. I want to apply restraints on these rigid
Can anyone let me know how can I apply restrains on only these rigid
residues, so that do dont move much during simulation and leave other
residues without any restraints..

Thank you
