I am trying to measure the angle between two domains of a protein that
opens and closes. I have seen previous posts that mention using measure
inertia to calculate the angle between two principal axes. However I am
trying measure the dihedral angle between the two planes (the two domains)
of the protein. Is there a script that does this or can you suggest a
better approach? Thanks.
