Re: [AMBER] mm_pbsa statistics problem

It seems that you have 40 snapshots, but the "com.all.out" file contains
multiple previous trial runs with one or two snapshots. You need to
completely clean up the working folder before starting a new job. The
script would keep append at the end of the .out file. This will screw up
the later statistics analysis.

All the best,
Ray
