If you want to run mm_pbsa_statistics.pl for a single traj. version of
MM-PBSA, you need to set calc_delta to "1", for a three traj. version to "2".
If you want to calculate a decomposition per residue, you need to set
calc_decomp to "1", for a pairwise decomposition to "2", for no decomp. to
"0".
So the call for a 3-traj. version with decomp. per residue would be:
mm_pbsa_statistics.pl 2 1 mysystem_statistics.in mysystem_statistics.out
With snap_min, snap_max you can optionally restrict the number of snapshots to
consider in the analysis to the intervall of [snap_min, snap_max].
Let me know if it doesn't work!
