Overview of ParaCell package for indexing in powder diffraction

This article describes the crystallography package ParaCell, which integrates several indexing methods. All methods share the basic infrastructure of the program, which uses GPUs to evaluate the correctness of the unit cell. The individually implemented indexing methods in the program are presented along with a comparison with other indexing software. The success and time requirements were tested on several data sets, including orthorhombic, monoclinic and triclinic examples.
