Hi everyone, As I wrote yesterday, I'm having problems running stable simulations with vsites and constraints in all bonds in different time-steps using gmx-4.0.2. As long as the dna strand does not cross pbc, the simulations run fine (the longest I did was 5ns). The dna topology was generated wit

Hi everyone, I'm having problems running an md simulation (with gmx-4.0.2) using vsites and a time step of 4fs. I did generate the tpr with pdb2gmx. The problem seems to occur when the molecule crosses pbc, since the first sign of the simulation not working fine after ~3ns is " Warning: 1-4 int
