Figure 2
HKL2MAP profiles. (a) d′′/sig(d′′) as a function of resolution. The graph shows the signal to noise from the anomalous differences. In the red part of the graph the anomalous signal is considered to be nonexistent. (b) Profiles of correlation coefficients between observed and calculated Bijvoet differences. (c) Contrast between the variance in the electron density in the protein region and in the solvent region for a given phase set as a function of cycle number with phases calculated based on the original (red) or inverted (blue) substructure. (d) Initial experimental electron-density maps at 7 Å resolution (original) contoured at at 1σ obtained from SHELXE; the final model has been displayed to assess the map quality. (e) d′′/sig(d′′) as a function of resolution as in (a) but using calculated anomalous differences from the final refined HCV nE1 model.
