Hi Nadine,
I encountered the same errors for a few of my several hundred snapshots
with mm-pbsa and amber_8_ - so this has nothing to do with the version
of amber. I also did not have to increase MAXAT for running mm_pbsa, so
the problem is also not related to your increased MAXAT value. I guess
the best workaround is to skip the sanpshots for wich molsurf is unable
to calculate the surface(?). Of course it would be nice to know what's
going on...
Best,
Oliver
