[gmx-users] question about g_sgangle

[jeremy adler]

Hi,

When i used g_sgangle, i specified 2 index groups of 3 atoms each and gave
the -oa flag to get the angle between them. I got two columns of output
(besides the time index) - one with much larger values on the right (they
look reasonable) and one with much smaller values on the left. what is the
difference between these two outputs?
