The only programs/methods that make a distinction between "ligand",
"receptor", and "complex" are MM-PBSA and LIE. You can use energy
decomposition in MMPBSA.py to get a qualitative understanding of
interaction energies, or the "energy" command in cpptraj may suffice for
your needs as well (see the documentation for each to help you decide which
method will be most helpful to you).
