[gmx-users] g_sgangle

[Chih-Ying Lin]

Hi
In manual, it says.....

-oa: Angle between the two groups specified in the index file. If a
group contains three atoms the normal to the plane defined by those
three atoms will be used. If a group contains two atoms, the vector
defined by those two atoms will be used.


one  group contains 3 atoms
the other group contains 2 atoms.

After the command g_sgangle, I got a output file with three columns.
what does each of the three columns represent?

Thank you
Lin
