[gmx-users] g_angle between three atoms

[Victor Rosas Garcia]

My guess is that g_angle is taking the atom order for the bond angle
from the topology.

Hope this helps

> Hi all. I'm interested in calculating a specific angle between three atoms situated in adjacent cellulose polymer chains. So I made the following index groups:
> Group     8 (a_3194_a_2348_a_4463) has     3 elements
> Group     9 (a_4463_a_3194_a_2348) has     3 elements
> Group    10 (a_2348_a_4463_a_3194) has     3 elements
>
> Notice how its the same atoms arranged in different order, yet GROMACS calculates the same angle over and over, the one Im NOT interested in. Any tips?
