Daria,
Try using earlier version of NAMD. 2.7b2 is a beta version.

> I'm trying to run protein MD in Amber FF using NAMD 2.7b2 on 4 local CPUs. The problem is that I have to launch NAMD several time to start a successful run.
> That means, starting NAMD in absolutely the same conditions - same folder, same input files and same files currently in the folder (FFTW_NAMD_2.7b2_Linux-x86_64-MPI.txt is being manually removed after each unsuccessful run) has a different result.

> Do you have any suggestions of how this could happen? Could AMBER in NAMD be dependent on some pseudo-random number generated from time-seed?
