Dear Arnon et al: My understanding of the Shannon/Nyquist sampling theorem is admittedly extremely rudimentary, but I think aliasing can result if an arbitrary brick-wall resolution cut-off to the data is applied. So let’s say there are real data are to 2.0 Å resolution. Applying the 2.2 Å cut

Dear Kay. Arguably, the resolution of a structure is the most important number to look at; it is definitely the first to be examined, and often the only one examined by non-structural biologists. Since this number conveys so much concerning the quality/reliability of the the structure, it is not

Hi everybody, since we seem to have a little Easter discussion about crystallographic statistics anyway, I would like to bring up one more topic. A recent email sent to me said: "Another referee complained that the completeness in that bin was too low at 85%" - my answer was that I consider
