There are quite a few examples in the amber9/test/rem_* directories. Make
sure that "make test.sander.REM" gives good results for your system, and study
those examples to see how (if at all) they differ from your inputs. That
might provide a clue.

Also, just run short versions of these jobs on a desktop machine (i.e. without
the queuing system.) It sometimes happens that outputs or errors get lost
that you could see if you ran it manually.

...good luck...dac
