Hi all,
I am encountering in a very strange problem. Feeding a protein (after minimization) to a position 
restraints simulation after few steps (10-20) I am getting this crash error:
"Number of grid cells is zero. Probably the system and box collapsed"
However, submitting with the same input a simulation with "no" position restraints the runs goes 
fine. I tried using posrefc 1000 and lower (200). Same result.
Any suggestion?
