WebThis article describes the implementation of real-space refinement in the phenix.real_space_refine program from the PHENIX suite. The use of a simplified refinement target function enables very fast calculation, which in turn makes it possible to identify optimal data-restraint weights as part of routine refinements with little runtime cost. Webphenix.refine can be given a reference model that is used to steer refinement of the working model. This technique is advantageous in cases where the working data set is low …
