The problem is that the .tpr file tells me that the monitoring is
being made between all pairs. I want only the pairs aminoacid1-ligand,
aminoacid2-ligand etc and not aminoacid1-aminoacid2. This kind of
monitoring, i.e., between all possible pairs, gives me .edr files that
are 1Gb or more in size. That is a problem since I need to do the same
type of analysis for 61 more complexes.
So, again, I need to monitor only the pairs in which one of the
members is the LIGAND and the other is one of the aminoacids of that
huge list I posted in the energygrps.
