Dear All,
We are currently running a residue-based CG simulation of a membrane  
protein system with explicit solvent and 10 fs timestep. We are using  
Langevin Piston for Temperature and Presssure control. When the  
program becomes unstable, we restart the simulation from the last  
written snapshot using all the files .vel, .coor and .xsc.  We check  
that the final written energy values of the previous run match the  
initial values of the next run. Surprisingly, the new run goes on  
without any further problem. Should we worry about the fact this new  
run is not the continuation of the previous run, but a completely  
independent run? Is there any randomness in Langevin Piston dynamics?
Thanks a lot!
Demet
