WebPhenix is a comprehensive software package for macromolecular structure determination that handles data from any of these techniques. Tasks performed with Phenix include data-quality assessment, map improvement, model building, the validation/rebuilding/refinement cycle and deposition. Each tool caters to the type of experimental data. Webphenix.refine is a program within the PHENIX package that supports crystallographic structure refinement against experimental data with a wide range of upper resolution limits using a large repertoire of model parameterizations. It has several automation features and is also highly flexible. 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. hanfkaiser
