[gmx-users] gangle function to calculate the angle of the vector with the x and y axes

[Yan Shen]

Dear gromacs users,

I would like to calculate the angle between vector and x/y axes. When I
search the website there is a post about for gangle function add option to
calculate the angle of the vector with x/y axes. (see
https://redmine.gromacs.org/issues/1619 ) And in the post the target
version for this feature is 5.1. However, when I looked up gromacs versions
after 5.1, even in the latest gromacs manual there is still no option for
x/y axes (http://manual.gromacs.org/programs/gmx-gangle.html). I'm
wondering if I misunderstood the fix for this feature or is there any
particular version that has implemented this function.

Thanks,
Yan Shen
