SENDePSIC

Tools for exploring atomic structure from radial-profile and concurrent 4D-STEM–EDX datasets.

View on GitHub

SENDePSIC is a Python package for exploring atomic structure and crystal phases through three-dimensional radial-average and radial-variance profiles, developed at electron Physical Science Imaging Centre (ePSIC), Diamond Light Source (United Kingdom). It also supports analysis paths for concurrent 4D-STEM–EDX experiments that are currently available at ePSIC.
