Hi:
I want to make a simulation of a small pepetide in a box of water but I want to freeze or restrain the movement of all water molecules that have a distance grater that 3 A from the protein surface. Right know the water that are within 3 A of the protein, have a different residue name (SHL) and the other water molecules have the normal resname (SOL) How I could do the restrain???
use make_ndx to make an index file and freeze all SOL

Thanks.
