2009-03-16 Thread Andreas Boozo Frank
Dear Gromacs-Users, we have the following problem: after running several hundred nanoseconds of a peptide (Gromos FF 53a6) in spc-water (NpT ensemble), we recognized that the tolerance of shake (all-bonds were constrained) was wrongly adjusted: instead of calculating with shake_tol = 0.0001, t
