Hi all,

I am trying to figure out the best way of reporting changes in dimer
orientations between three structures. I have an apo, a drug-bound, and a
homolog dimer structure. I had originally decided to calculate the angle
from the rotation matrix generated by LSQKAB, but the translational
component is oriented in opposite directions (translation vector of -22.9,
3.2, 10.8 versus 22.4, -3.4, -17.1). I've only ever seen these types of
orientation shifts reported in degrees, so I was wondering how other people
dealt with accurately reporting these numbers in their manuscripts. Did you
include the translation vectors in the text or just rely on figures and
arrow to make your point?

Thanks for your time,
Katherine
