Autoindexing diffraction images with iMosflm

An overview of autoindexing diffraction images based on one‐dimensional fast Fourier transforms is presented. The implementation of the algorithm in the Mosflm / iMosflm program suite is described with a discussion of practical issues that may arise and ways of assessing the success or failure of the procedure. Recent developments allow indexing of images that show multiple lattices, and several examples demonstrate the success of this approach in real cases.
