Why on earth is the rsrz score one of 5 criterions for a good PDB? There is no way to calculate it on your own and the proponents, like G. Kleywegt who inititated it, have their server (UPPSALA eds) since 2004 not available for individual uploads. It would be acceptable, if the REAL SPACE R-Factor would be one of these criterions, in case REFMAC5, PHENIX (or CNS) would calculate it, but no one bothers to implement it in a user-friendly way (CNS might be an exception). In CCP4 overlapmap yields only nonsense values these factors.
