title: Untangle, a tool for filtering overlapping diffraction patterns from multicrystals.
abstract: Standard crystallographic data-processing protocols are based on single-crystal models; data from aggregates of multiple crystals with different orientations are difficult to process. In certain cases, it is possible to separately index the diffraction patterns from the dominant crystals in the aggregate. Untangle is a program designed to identify and eliminate overlapping spots from such patterns in order to improve data quality. The program has a Python core with a simple and highly portable graphical user interface, permitting visual verification of the process and interactive modification of the overlap threshold. The software is available under an open-source license.
