[gmx-users] Windows Gromacs Issue

[Raj Badhan]

Dear All,
I'm running a simulation of a protein in the windows version of 
gromacs.
I have three versions of the same protein, and am running version 1 
on one PC (500ps simulation) which is running fine.
I run version number two, and when initiating the final MDRUN to 
start the simulation, mdrun gets to the point of :

starting mdrun:
250000 steps etc....

Before backing up the trr files and exiting with:

Back off! Just backup step0.pdb to ......
Wrote PDB with previous and current coordinates

before the the command prompt crashes saying MDRUN caused it 
to end.
I have run this simulation on two PC (windows XP) and they both 
end the same way, and I have no idea why.
(The 20ps position restrained sim. works OK too).
Any ideas?
Many thanks
