I am trying to analyze the hydrogen bonds of my simulations by g_hbond.
I am using an index file where I created two groups: one with acceptor atoms
(carboxylic oxygen atoms in my structure) and another group with the water
molecules.
I got a segmentation fault with the message:
Select a group: 6
Selected 6: 'PEI_&_OC'
Select a group: 3
Selected 3: 'Water'
Checking for overlap in atoms between PEI_&_OC and Water
Calculating hydrogen bonds between PEI_&_OC (1296 atoms) and Water (258 atoms)
Found 86 donors and 1382 acceptors
Reading frame 0 time 10000.000 Will do grid-seach on 15x15x15 grid,

Segmentation fault (core dumped)
The number of donors is correct (I have 86 water molecules) but the number of
acceptors is not.
The number of acceptors is correct. Water oxygens can be acceptors, so 1296 +
86 = 1382.
Please, can someone tell me what I am doing wrong?
What GROMACS version are you using?
