Phenix refinement strategy
WebThe standard ERRASER-Phenix pipeline consists of three major stages: an initial Phenix refinement, followed by iterative ERRASER refinement, and a final Phenix refinement (Fig. … Web8. nov 2024 · At each step of coordinate refinement, Phenix expands the asymmetric unit coordinates to a full unit cell (as required by sander ), combines energy gradients returned from Amber (in place of those from its internal geometric restraint routines) with gradients from the X-ray target function, and uses these forces to update the coordinates.
