Thanks for your reply.

Good to know this ... and this would be a good opportunity
to learn how to use GitHub (I'm not an active programmer).

The next release of cpptraj will be able to access sander energy

Good to know this, too.
(Actually, I used sander ... with very very short simulation dt ...
to check the accuracy of the charmm-specific terms since sander
generates those terms in the output.)

I just wonder whether 'eander' accepts one or two masks.
The whole purpose that I wrote new codes is to compute energy
for specific regions and for interaction between two specific regions
of interest (since if only the total energy was what I want I could
use sander API).
