quantEM is an open source Python toolkit for quantitative electron microscopy: imaging, diffraction, ptychography, tomography, and spectroscopy. Built on PyTorch, it runs on CPUs and GPUs and integrates deep learning.
What quantEM is, how to install it, and how the package is organized.
Drift correction and lattice analysis for atomic resolution images.
Bragg disk detection, orientation and phase mapping, strain mapping, and diffraction simulation for 4D-STEM.
Iterative and direct ptychography, from quick previews to multi-GPU reconstructions.
Alignment, preprocessing, and 3D reconstruction of tilt series.
Analysis of spectroscopic signals such as EDS.
quantEM is developed openly on GitHub, with worked examples in quantem-tutorials. It is free software under the MIT license.
