Hello, I have a question on refinement of macromolecules. I like to apply 180 degree rotation to the side chain of a particular residue about a particular bond and see, which one (before or after applying rotation) agrees well with the observed x-ray data (based on R factors and electron density map). Can someone advise, what could be the best way to do this? I like to do the same operation on multiple structures which are already refined. Regards, hena
