pyxem is an open-source (GPL v3) python library for multi-dimensional diffraction microscopy.

The package defines objects and functions for the analysis of numerous diffraction patterns. It has been primarily developed as a platform for hybrid diffraction-microscopy based on 4D scanning diffraction microscopy data in which a 2D diffraction pattern is recorded at every position in a 2D scan of a specimen.

pyxem is an extension of the hyperspy library for multi-dimensional data analysis and defines diffraction specific Signal classes.

Installation instructions and tutorial examples are available here .

Basic Documentation is available here.
