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?
