Of Problems and Opportunities – How to Treat and How to Not Treat Crystallographic Fragment-Screening Data

Abstract

SUMMARY: In their recent commentary in Protein Science, Jaskolski et al . analyze three randomly picked diffraction data sets from fragment-screening group depositions from the PDB and, based on that, claim that such data are principally problematic. We demonstrate here that if such data are treated properly, none of the proclaimed criticisms persist.

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.
