You have to make sure that AMBERHOME points to your Amber 12 release, and
if you are just calling "sander" or "pmemd" that the Amber 12 bin/
directory appears in your PATH variable before the Amber 11 bin/ directory.

The reason you gave for your problem does not make sense.

You never stated what your problem was besides not being able to calculate
the binding energy of each residue (which is nowhere near enough
information for us to be able to help). Please be specific with your
problem, providing what _exactly_ you tried and the output you got from
those tries.

Also make sure that you can work through the related tutorials at
