Free R factors for rebuilt models, re-refined original models and composites of rebuilt models. Free R factors for each of the 20 rebuilt models for each structure from the PDB are illustrated as small diamonds. The free R factor for the original PDB entry, after refinement without solvent or ligands, is indicated by a large open triangle. The free R factor of a composite model corresponding to simple averaging of density from the 20 rebuilt models (including an implicit solvent model obtained as part of the refinement process) and calculated by simple averaging of complex structure factors based on all the component structures is indicated by a large filled square. |
