Histogram matching as a new density modification technique for phase refinement and extension of protein molecules
Abstract
A new density modification technique - histogram matching - is being developed with encouraging results. Its application to the known structure of pig 2Zn insulin refines the 6500 1.9 Å MIR phases from a mean error of 60° to one of 46°. With these refined phases as a starting point for phase extension to 1.5 Å, the mean error for the final 13 000 phases is 46°. The original 1.9 Å phases continue to refine during the phase extension to a final mean error of 40°. A comparison is made with similar calculations already published.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
