Abstract
An improved method of crystallographic structure refinement, especially suitable for large molecules, is described, it is based on simultaneous minimization of a realistic potential-energy function and a crystallographic residual. The method has already proved its worth in the final stages of refinement of two structures; an application to crude wiremodel coordinates of a small protein is described and evaluated.
