Dear Amber Users

I am trying to calculate the pairwise energy decomposition using MMPBSA.py.
Total frames I considered for this calculator is 25. my residues mask is

idecomp=3, print_res="29; 31; 33; 37-39; 42; 44; 49; 52; 84; 86; 88; 90;
92-97; 137; 138; 140; 142; 160; 170; 204; 206-213"


This residue mask consists of all interface residues from the receptor and
its cognate. These are total 35 residues.

My question is when I finished calculations each pair of interface residue
printed 35 times with different energy values on which energy value we
need to consider and from where these energy values are coming however I am
consider 25 frames for these calculation, Or maybe I did not set the mask
properly

Do I need to get the average of all these 35 times energy values to get
this particular pair of decomposition energy? Please guide
