[gmx-users] g_angle for calculating dihedrals

[Amit Choubey]

Hi everyone,

I was looking at calculation od dihedrals using g_angle. I did not
understand what the output of this tool is, along the x-axis we have angle
(in degrees) but what do we have along the y axis . Does y-axis show the
fraction of dihedrals having that specific angle? It does seem so by adding
all the fractions but i need to make sure.

Just to be sure that you know what i am talking about i first used make_ndx
to make a group of 4 atoms (whose dihedral has to be calculated) . Then i
used

g_angle -f confout.gro -n index.ndx -type dihedral

where index.ndx has the indices for all the relevant atoms stored in a
group.

Thank you,

Amit
