Figure 10
Plot of the real-space difference density Z score (as defined in §5.8 for a Leu side chain with simulated normally distributed random errors in the electron density (resolution cutoff dmin = 2.5 Å) based on the atomic radius limits defined in §5.6 as a function of the atomic B factor. The suggested level of significance for RSZD (3σ) is also shown (dotted line). This shows that RSZD is always well below the level of significance for a correct model regardless of B factor and is uncorrelated with the B factor. The plots of the real-space R and the real-space sample correlation coefficient from Fig. 7 are shown for comparison. |
