In their recent commentary in Protein Science, Jaskolski et al. analyzed three randomly picked diffraction data sets from fragment-screening group depositions from the PDB and, based on that, they claimed that such data are principally problematic. We demonstrate here that if such data are treated properly, none of the proclaimed criticisms persist.
Keywords: PanDDA; compositional heterogeneity; conformational heterogeneity; fragment-screening; group depositions; low-occupancy ligands.
