Crystallography indexing
Web2.3. Diffraction geometry and indexing As of this writing, we are routinely indexing and integrating MicroED data for various samples using MOSFLM/AIMLESS (Leslie & Powell, 2007; Evans & Murshudov, 2013) and XDS (Kabsch, 2010 b). As these software packages are primarily developed for X-ray crystallography, it is worthwhile to keep the unique ... WebMay 1, 2024 · Resolving the indexing ambiguity of the XFEL diffraction data. After integration, the XFEL diffraction data were scaled, post-refined and merged. The post-refinement parameters are provided in Table 1. From the IOTA integration statistics, 316 integrated images had measurable diffraction to 2.0 Å resolution.

WebIn crystallography there are conventions as to how the indices of planes and directions are written. When referring to a specific plane, "round" brackets are used: ( hkl) When referring to a set of planes related by symmetry, then "curly" brackets are used: { hkl } These might be the (100) type planes in a cubic system, which are (100), (010 ... Miller indices form a notation system in crystallography for lattice planes in crystal (Bravais) lattices. In particular, a family of lattice planes of a given (direct) Bravais lattice is determined by three integers h, k, and ℓ, the Miller indices. They are written (hkℓ), and denote the family of (parallel) lattice planes (of the given Bravais lattice) o…
