From rotation images to a merged MTZ

Spot finding, indexing, 3-D profile-fitting integration, point- and space-group determination and Aimless-style scaling, computed on your GPU. Reads Eiger HDF5/NeXus (bitshuffle-LZ4) and Pilatus CBF, also inside .tar, .tar.bz2, .bz2 or .zip.

Load images first. Find spots & index shows the lattice and possible space groups; Run all continues from there (it re-uses spots and indexing already done).

Resolution estimate (spots) — Runs with spot finding: the resolution where strong spots thin out, per detector sector (anisotropy) and against the detector edge.

Scroll or pinch to zoom, drag to pan. Square marks are predicted reflections, circles are spots found on this image.
