(a) Plot of the atomic radius limits used in the distributed versions of MAPMAN and SFALL as a function of the atomic B factor, showing the large discrepancy in the values used; (b) plot of the real-space R 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 shown in (a). This shows the effect on the RSR of the large difference in radius limits and also the dependence of the RSR on the B factor in each case. |
