Coordinate transformations in modern crystallographic computing
TL;DR: A review of 4 x 4-matrix notation and of tensor formalism focused on crystallographic applications is presented and a discussion of examples shows how this notation simplifies tasks encountered in crystallographic computing.
Optimal structure determination from sub-optimal diffraction data.
Wladek Minor,Marcin Cymborowski,Dominika Borek,David R. Cooper,Maksymilian Chruszcz,Zbyszek Otwinowski +5 more
TL;DR: The latest version of the HKL-3000 system as discussed by the authors integrates data collection, data reduction, phasing, model building, refinement, and validation to accelerate the process of structure determination and has proven its high value for the determination of very high-quality structures.

Taking a look at the calibration of a CCD detector with a fiber-optic taper.
TL;DR: After performing a partial flat-field calibration for the ADSC Quantum 210r CCD detector, it was confirmed that the detector operates within specifications, but as a secondary check it was decided to scan a single reflection across one-half of a detector module to validate the accuracy of the calibration.

The crystallographic fast Fourier transform. Recursive symmetry reduction
TL;DR: The interaction between the grid size factorization and the symmetry operators and its influence on the algorithm design are discussed and the central idea is a recursive reduction of the problem to a series of transforms on grids with no special points.

TL;DR: In this paper, the rut pathway of pyrimidine catabolism is a novel pathway, which allows pyridine bases to serve as the sole nitrogen source in suboptimal temperatures.
