Great Lakes Microscopy Society Webinar Series Part 4: Large Data Processing and 4D-STEM
Time:
May 21, 2026 12:00 PM EST
Abstract:
We will focus on how to load, visualize and process large 4D STEM datasets using hyperspy and pyxem. The goal is to help people feel confident handling large multi-GB datasets and give techniques and tricks for visualizing and processing them. This is part 1 of 2 in which we will talk about lazy data processing and out of memory operations. This will provide a solid base for further data processing with the goal of developing skills for understanding nanobeam diffraction for measuring phase contrast, strain, creating phase maps, virtual imaging and quantifying disorder/order within a material. We will also work though and discuss techniques like in-situ 4D-STEM, and work through processing a large 5D-STEM dataset.
Presenter: Dr. Carter Francis, Direct Electron
Carter Francis is a Research and Development Scientist working with Direct Electron to developing software and hardware for materials science research. He did his PhD under Prof. Paul Voyles at UW Madison. There his work was on characterization of disordered materials using 4D STEM and in situ 4D STEM. In addition to working for Direct Electron, Carter is a member of the HyperSpy steering council and is the lead developer for the 4D STEM analysis package pyxem.
