We have 1.5A resolution data for a heterodimeric protein with linked A and B chains. Phenix MR has produced a promising solution. We would now like to perform an initial refinement using Phenix with the A chain and B chain individually treated as rigid bodies.
Is this possible with Phenix and if so how?
