Data Processing and Analysis Software
The majority of the data acquired at the SuperSTEM are currently in theGatan Microscopy Suite® (GMS) software .dm3 and .dm4 file format. A free of charge configuration of Gatan Microscopy Suite® (GMS) software and information on the commercial versions and plugins can be found here.
For those users who have access to the DM™ software, a variety of useful freeware scripts can be found in the Digital Micrograph™Script Database, hosted by FELMI at the Graz University of Technology.
Great tools for DM™, as well as examples and tutorials for scripting can be found at Dave Mitchell's Digital Micrograph™ Scripting Website.
If you have access to DM™ but not the Gatan Spectrum Imaging package look out especially for Dave Mitchell's SITools (very handy!!).
Nion Swift is an open source scientific image processing software platform integrating hardware control, data acquisition, visualization, processing, and analysis using Python. Nion Swift is easily extended using Python. It runs on Windows, Linux, and macOS.
While being developed for the operation of Nion electron microscope instruments, it is also useful as an offline tool to visualize, process, and analyze data. It is being developed with the intention of supporting additional instrumentation and fields.
Advanced Data Processing and Simulations
HyperSpy is an open source Python library which provides tools to facilitate the interactive data analysis of multi-dimensional datasets that can be described as multi-dimensional arrays of a given signal (e.g. a 2D array of spectra a.k.a spectrum image).
HyperSpy aims at making it easy and natural to apply analytical procedures that operate on an individual signal to multi-dimensional arrays, as well as providing easy access to analytical tools that exploit the multi-dimensionality of the dataset.
Its modular structure makes it easy to add features to analyze different kinds of signals.
HREM Research provides a selection of commercial and free ware tools for DM™.
We are proud to serve as an Associated Demonstration Site for several HREM research tools; including MSA, SmartAlign and DeConvHAADF.
The Dr. Probe software is a free tool package for multi-slice image simulations in high-resolution scanning and imaging transmission electron microscopy. It comprises a graphical user interface version for direct visualization of STEM image calculations, as well as a bundle of command-line modules for more comprehensive calculation tasks.

It includes parallel, data-streaming implementations of both the plane-wave reciprocal-space interpolated scattering matrix (PRISM) and multislice algorithms using multicore CPUs and CUDA-enabled GPU(s), in some cases achieving accelerations as high as 1000x or more relative to traditional methods. Prismatic is fast, free, open-sourced, and contains a graphical user interface.
EELSMODEL is software for the quantification of quantify Electron Energy Loss (EELS) spectra by using model fitting. This provides a more accurate and reliable way of extracting quantitative information from EELS spectra compared to the conventional quantification technique.
The aim of this program is to give as many people in the EELS community access to an improved method for quantifying spectra with a more or less user friendly program.
