2012-10-17 Thread Netaly Khazanov
Dear All, I've performed TMD simulation using NAMDprogram. I'd like to calculate PMF plot based on the frames that were taken from TMD simulations by using GROMACS. The coordinate of reaction is RMSD of backbone. The first step is to do Umbrella sampling. The question is how fix the position of
