[gmx-users] g_hbond

[Nilesh Dhumal]

Hello,

I am calculating g_hbond for water system.  I have a question about
specifying two group for calculating hydrogen bond.

Do I specify atoms in triplet(O-H---O)?
Can I specify O-H as one group (Donor-Hydrogen) and O in other group
(Acceptor)?
Default  -r cutoff is 0.35nm. Is the distance between hydrogen---acceptor
or distance between donor---acceptor?

Thanks,

Nilesh
