Since there is now a growing wish by referees to judge the underpinning data for a submitted article it is timely to provide a summary of the data evaluation checks required to be done by a referee. As these checks will vary from field to field this article focuses on the needs of biological X-ray crystallography articles, which is the predominantly used method leading to depositions in the PDB. The expected referee checks of data underpinning an article are described with examples. These checks necessarily include that a referee checks the PDB validation report for each crystal structure accompanying the article submission; this check whilst necessary is not sufficient for a complete evaluation. A referee would be expected to undertake one cycle of model refinement of the authors biological macromolecule coordinates against the authors processed diffraction data and look at the various validation checks of the model and Fo-Fc electron density maps in e.g. Phenix_refine and in COOT. If the referee deems necessary the diffraction data images should be reprocessed (e.g. to a different diffraction resolution than the authors submission). This can be requested to be done by the authors or if the referee prefers can be undertaken directly by the referee themselves. A referee wishing to do these data checks may wish to receive a certificate that they have command of these data science skills. The organisation of such voluntary certification training can e.g. be via those crystallography associations duly recognised by the IUCr to issue such certificates. |
