I'm still not sure about this 1-4 interactions, when I want to calculate the energy between two groups (lets say one residue and the rest of the protein) should I sum everything (including the 1-4 interactions) or should I only include the SR interactions.

1-4 interactions are intramolecular and thus should not be included in 
intermolecular energies.  If you're using PME, decomposing the long-range 
component to the electrostatics term is challenging.
