Re: [AMBER] MMPBSA.MPI running issue

Hi,

If you have Amber11 available, try setting the variable "use_sander=1" in
your MMPBSA input file (in the &general section). I'm not sure what's
happening here, but your filesystem seems to be choking on simultaneous file
accesses or something like that (perhaps the way NAB handles files is
causing some grief, maybe you'll have better luck with sander, although it
will take longer).

HTH,
Jason
