Dear All,
        
        
        With the EM cryo data,
          I have compared the function of phenix.real_space_refine of
          Phenix10 and Phenix1.9-1692. For the Ramachandran favored, the
          new version is about 90%, the old version is about 92%. For
          the clashscore by Molprobity, the new version is about 30, the
          old version is about 20. Molprobity indicated the clashing
          atoms were systematically existing in the whole molecule,
          rather than on specific parts of the protein which may be
          indication of bad modelling.
        
        
        Clearly the clashscore
          of 30 is unacceptable. Will you please give some advise on how
          to improve the function of new version of Phenix, considering
          adding H was not suitable as for the resolution was poorer
          than 4.0 A?
        
        
        Smith
