Abstract

A bundle of notebooks for the processing of 4D-scanning transmission electron microscopy data in Pyxem. Each notebook is well commented, though referencing the websites: https://www.pyxem.org/en/stable/ https://hyperspy.org/ is recommended if deeper understanding of the data structures, of the mathematical processes underlying the operations are desired. Features available in this release are: Cropping and initial processing of the STEM image High-angle annular dark field (HAADF) imaging Fourier transform and power spectrum production Simulation of electron spot diffraction patterns from CIF file Fast template matching for crystallographic assignment To get started: Use the Pyxem.yml file to construct a suitable environment. Run jupyter notebooks and start analysing. Generally CroppingAndProcessing.ipynb should be the first port of call. The typical 4D-STEM file is massive (>1GB) and so binning and cropping should be used liberally to reduce the file size as required (256x256 pixels is often perfectly sufficient for the diffraction axes, for instance).
