[gmx-users] use of g_hbond

[soumadwip ghosh]

Dear Alex,
             as you can see in my previous mail, I have made groups in the
index files using make_ndx (gp no 10-17). My question is with the kind of
groups I have, how can I calculate H bonding between chain A and chain B in
presence of sodium . Should I merge gp 13 and 2 together and make a gp (say
18) and then use g_hbond for groups 18 and 14?
