Thank you Sahil, I will try VMD plugin for H-bond analysis.
Thank you Justin for your reply, it looks like gmx hbond considers only one N-H
as donor when part of NH2 group. Please take a look at this file.
This is what gmx hbond does by default, see gmx help hbond:
H-bonds between the same donor and acceptor, but with different
hydrogen are treated as a single H-bond. Mainly important
This is a very different situation than claiming the NH2 group simply
isn't accounted for.

Subject: [gmx users] Terminal amide hydrogens not included in H-bond analysis
Hello gromacs users,
My peptide has an amide group at the C-terminus. Hydrogen bond analysis using
gmx hbond does not take into account H-bond donors (NH2) from the amide group
(Note: this NH2 is considered as a residue according to opls ff). What might be
