Indeed, I found a related sentence, although I would say that carnal is
more a complement to anal than a substitute, since carnal does mostly
structural analyses while anal does energetic analyses.

I'm not aware of any possibilty to do this with carnal, but somebody
else might know better?

I'm not quite sure what you want to do - if you want to break down
energies for single snapshots of your trajectory into E-ele, E-vdw,
E-internal, ..., mm_pbsa should be appropriate.
If you want to post-process a whole trajectory, you might want to have a
look at the IMIN=5 option for sander. I have never used this, so others
might know more.
If you are interested in more detailled analyses of internal energies,
anal seems to be the right program.
Best regards
Holger
