In addition to what Christina suggested, you can also extract the energies
directly from the remlog files. I'm not sure if cpptraj does this (I know
it reads remlogs, but I'm not sure if it will extract the energies into a
data set... you could always try it and see what the manual says about it).
If you plan on using cpptraj, I suggest updating to the latest version of
AmberTools 14, as there have been numerous cpptraj improvements since Amber
12.
