Hello, I am studying a protein that has an amino acid modeled as a two-state rotamer in the crystal structure. I would like to quantify the probability of each conformation, so I thought of doing a FEP calculation. As I haven't seen much about this in the mailing lists, save for a D- L- amino ac

Hi gmx-user! I've a great problem: two months ago I installed LAM on my centrino duo, debian -kernel 2.6. Later I compiled gromacs enabling mpi, and everything was working well until four days ago. Now the simulation time is increased like if there is only one processor (it takes twice time than
