I am trying to run MD on a region of protein. I tried the following things
1. Made a huge box, centered the protein and then filled the box with
water and included freeze groups in the mdp file.
problem: The run is not short enough, since all the water
molecules in the huge box is moving anyway
2. Made a small box which sees only an indexed group of atoms and filled
that box with water.
problem: similar to chopping the protein, the atoms seem to be
rotating a lot, the run does not get completed since the atoms move a
producing a huge rmsd and huge rotations (gives me error like rotated
What would be the best way to do a quick run on a part of the protein
