Data Processing and Analysis Software
The majority of the data acquired at the SuperSTEM are in
the Gatan Digital Micrograph™
(DM™) .dm3 file format.
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!!).
If you do not have
access to DM™ a very good freeware alternative is the Java-based ImageJ image processing software, available for all
major OS platforms. ImageJ has an
embedded plug-in that can read .dm3
Analysis of spectra and
Spectrum Images, including Gaussian fitting and principal component analysis
(PCA) can also be preformed in ImageJ
though the Cornell Spectrum Imager (CSI).
Cornel CSI can be downloaded as an ImageJ
distribution or separate plug-in.
Data Processing and Simulations
Hyperspy is a powerful (line
command) all-inclusive multidimensional data analysis package, including
Principle Component Analysis and set of
functions for EELS data analysis and other spectroscopies.
HREM Research provides a selection of commercial and free
tools for DM™. We are proud to serve
an Associated Demonstration Site for several HREM research tools; including MSA and DeConvHAADF.
C. Koch is a freeware package for quantitative
simulations of TEM and STEM images. On the QSTEM page you'll find a comprehensive
tutorial and several useful examples.
EELSMODEL is a freeware used for the quantification of
EELS spectra by model fitting.
CTM4XAS is a freeware for the
simulation of transition metal core level spectra, including XAS, EELS, XES and XPS.
