[gmx-users] Error during mdrun

Hi Chetana (and Mark et al.),
Note that this can also be the infamous spinning -NH3 error, which has
been reported primarily for lysines previously on this list (tip:
search the archive). To be sure, as Mark stated, more information is
required. Specifically, at what step the crash occurred and which
atoms were involved. This information is given in the *0.log file.
Although the crash will be at the end of the file, the problem may
have gone on for some while and you will have to search for the first
hint of problems (LINCS warning), and check the atoms involved.
If the crash occurs early during your simulation, it is likely a
problem of equilibration/setup.
(Now why am I always lagging behind Mark with my comments?)...
Hope it helps,
