Squash: A Procedure for Phase Refinement and Extension of Protein Structures
Direct methods are now well established as an automatic method for the solution of small molecule structures. Features expected of the electron density are used to constrain the values of the unknown phases. The result is a map at atomic resolution from which atomic co-ordinates can be extracted by peak search routines.
