Andrews L, Bernstein H, Sauter N
Acta Crystallogr A Found Adv . 2023 Jul; 79(Pt 5):480-484. PMID: 37485824
A method is proposed for choosing unit cells for a group of crystals so that they all appear as nearly similar as possible to a selected cell. Related unit cells...

Bernstein H, Andrews L, Xerri M
Acta Crystallogr A Found Adv . 2023 Jun; 79(Pt 4):369-380. PMID: 37338213
Characterization of crystallographic lattices is an important tool in structure solution, crystallographic database searches and clustering of diffraction images in serial crystallography. Characterization of lattices by Niggli-reduced cells (based on...

Andrews L, Bernstein H
J Appl Crystallogr . 2022 Aug; 55(Pt 4):782-786. PMID: 35979069
Methods of generating random unit-cell data for testing software are discussed. Working within the space appears to be the most expeditious.

Soares A, Yamada Y, Jakoncic J, McSweeney S, Sweet R, Skinner J, et al.
Acta Crystallogr F Struct Biol Commun . 2022 Jul; 78(Pt 7):281-288. PMID: 35787556
KAMO and BLEND provide particularly effective tools to automatically manage the merging of large numbers of data sets from serial crystallography. The requirement for manual intervention in the process can...

Nguyen T, Phan K, Kozakov D, Gabelli S, Kreitler D, Andrews L, et al.
Acta Crystallogr D Struct Biol . 2022 Mar; 78(Pt 3):268-277. PMID: 35234141
One often observes small but measurable differences in the diffraction data measured from different crystals of a single protein. These differences might reflect structural differences in the protein and may...

Bernstein H, Andrews L, Diaz Jr J, Jakoncic J, Nguyen T, Sauter N, et al.
Struct Dyn . 2020 Jan; 7(1):014302. PMID: 31934601
In macromolecular crystallography, higher flux, smaller beams, and faster detectors open the door to experiments with very large numbers of very small samples that can reveal polymorphs and dynamics but...

Andrews L, Bernstein H, Sauter N
Acta Crystallogr A Found Adv . 2020 Jan; 76(Pt 1):79-83. PMID: 31908351
The transformations from the primitive cells of the centered Bravais lattices to the corresponding centered cells have conventionally been listed as three-by-three matrices that transform three-space lattice vectors. Using those...

Andrews L, Bernstein H, Sauter N
Acta Crystallogr A Found Adv . 2019 May; 75(Pt 3):593-599. PMID: 31041913
Algorithms for quantifying the differences between two lattices are used for Bravais lattice determination, database lookup for unit cells to select candidates for molecular replacement, and recently for clustering to...

Andrews L, Bernstein H, Sauter N
Acta Crystallogr A Found Adv . 2018 Dec; 75(Pt 1):115-120. PMID: 30575589
The unit-cell reduction described by Selling and used by Delone (whose early publications were under the spelling Delaunay) is explained in a simple form. The transformations needed to implement the...

Andrews L, Bernstein H
J Appl Crystallogr . 2016 Jun; 49(Pt 3):756-761. PMID: 27275134
Many problems in crystallography and other fields can be treated as nearest-neighbor problems. The neartree data structure provides a flexible way to organize and retrieve metric data. In some cases,...
