I would like to calculate the orientation of a group in my simulation
and cant figure out how to do it.
I have a protein in a membrane, a large part of this protein is in the
solvent and has a rigid-body like motion. I'd like to characterise that
motion by let's say monitoring the evolution of the principal axis of
I thought about g_gyrate, but could only retrieve moments of inertia,
not the proper axis.
I then thought about g_dipole, but it crashes when I ask for a subgroup.
Any thoughts on that?
Thanks in advance
