[gmx-users] problem running posre

[Alan Dodd]

Have you tried running for a short period without PR, then putting the output from that into PR again?  If the initial run is short enough, it shouldn't affect things too much, but may still randomise out whatever's causing the problem.

Subject: [gmx-users] problem running posre


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?

Regards

andrea
