Do you have a .gro file with both protein "in complex"? if you do you could
- gmx make_ndx -f proteins_complex.gro -o xxx.ndx
- r x (enter)
- r y (enter)
where x is the number of the first residue in chain A in the complex.gro
where y is the number of the first residue in chain B in the complex.gro
This should work... At least it worked for me and I just tried with one of
have a nice day,
