orix is an open-source Python library for analysing orientations and crystal symmetry.
The package defines objects and functions for the analysis of orientations represented as quaternions or 3D rotation vectors accounting for crystal symmetry. Functionality builds primarily on NumPy and Matplotlib and is heavily inspired by the MATLAB package MTEX.
If analysis using orix forms a part of published work please cite the paper (journal, arXiv).
Documentation is hosted on Read the Docs with a complete reference for functions and classes, as well as a user guide in the form of Jupyter notebooks. These notebooks can be inspected statically on the web page or via nbviewer, interactively in the browser by clicking the Binder link above and navigating to the doc/ directory, or on your own computer by downloading them and the corresponding data. We hope you find them useful!
