[gmx-users] mdp file for monitoring pair groups

I have created an mdp file with 202 groups for monitoring in the
energygrps string. Being 201 of these aminoacids which interact with
the 202nd which is the ligand. The problem is that I found out that
this does not work properly, and also does not work the way I thought
it would work. Well, the deal is that I want to monitor each of the
pair interactions, i.e., aminoacid1-ligand, aminoacid2-ligand,
aminoacid3-ligand etc. Is there a way I can do this with a single mdp
file, or should I create 202 different mdp files and -rerun 202 times
the same simulation (which sounds just as crazy as the idea i had
Here is what I have written for the energygrps:
energygrps          =  _S r_29 r_30 r_61 r_63 r_64 r_65 r_66 r_67 r_68

I would like some advice on the matter.
