Subject: AMBER: NTR force constant for restraint !!

To Amber Community,

I am new in doing protein MD simulations. I wish to perform MD initially cartisian restraining some of the resisdues at the biginning of the MD for about 35 ps. I am wondering how big the restraint force constant should be provided for almost no change/ least change in the catitian coordinate of the restrained residues.

Your suggestions would be highly appreciated,
