Comparison of backbone validation metrics for the atomic model of the RNA polymerase complex (PDB ID: 7bv2). (A) Comparison of the per-residue scores from MapQ, SMOC, SCCC, PHENIX, and FDR backbone score for the chain B of the atomic model, the red boxes highlights the residues selected for detailed analysis in the panels below. For Val 83 (B), Leu 98 (C), and Asn 109 (D), the panel shows a table with values of scores obtained with each metric and corresponding Z-scores; the residue fit in the target map (EMD-30210, grey) displayed at the recommended contour level and rendered in UCSF Chimera; the residues fit in the map rendered at a lower contour level.
