EMsoft: Series of Fortran programs which, among numerous other tasks, can perform dictionary indexing of EBSD and Transmission Kikuchi Diffraction (TKD) patterns.
MTEX: Matlab toolbox for analyzing and modeling crystallographic textures by means of EBSD or pole figure data.
AstroEBSD: Matlab package with indexing tools for EBSD patterns.
xcdskd: Python library with tools for Kikuchi Diffraction in the SEM, plus detailed Jupyter Notebooks explaining its use.
OpenXY: Matlab tool for performing cross-correlation analysis of EBSD patterns using real and simulated patterns.
