[AMBER] maximum distance for protein-ligand interactions in MM/GBSA

Hello everyone,

This question is addressed to those that are familiar with MM/GBSA. I have
many protein-ligand complexes and I want to do in batch mode MD and MM/GBSA
with per residue energy decomposition. In that context, it would be much
more convenient to select for each complex the residues that are within R
Angstroms from the ligand to be included in the residue decomposition of
the free energy. Is there any maximum distance Rmax from the ligand (e.g. 6
Angstroms) after which all interactions with the protein residues are
negligible? I can imagine that if the ligand has net charge then the
electrostatic interactions will require higher R value to cancel out.

Thank you in advance for any advice.
Thomas
