[gmx-users] Wrong pressure with "mdrun -rerun" option

[LuLanyuan]

Hello all,
>From the notes for gmx 4.0.5, the pressure and virial from "-rerun" should be correct. However, I did a test for a box of tip3p water and found the pressure results from rerun were different compared to the original results. For the first MD simulation , I simulated it for 200 ps and use the neighbor list update frequency 1. I used "g_energy" to extract pressure results and the results were 545.384 and 1153.55 bars for the MD and rerun, respectively. The gromacs version is 4.0.5.
Can anyone give me any clue?
Thanks.
Lanyuan Lu
