A common question for new GISAXS users is: "What software can I use to analyze my data?" Unfortunately, there is no single package that will allow you to perform any possible analysis. This is in part due to the diversity of possible kinds of data analysis one might want to do on GISAXS or GIWAXS images. The following lists a variety of packages that are available.
Contents
Data Viewing, Reduction, and Simple Analysis
These packages provide ways to view data, and perform simple operations (linecuts, etc.).
Geared towards 2D data
- Fit2D: A well-known package for treatment and conversion 2D scattering images.
- ImageJ: A generic tool for image treatment and analysis. Can be used to open and process x-ray detector images.
- view.gtk: A simple interface for viewing 2D data, calibrating your data into q-space, and extracting linecuts. Written by Lin Yang for the X9 beamline at NSLS. Installation requires (free) GTK libraries.
- GIXSGUI: Visualization and reduction package for GISAXS. Requires the commerical Matlab software. Written by Zhang Jiang.
Geared towards 1D data
- NCNR SANS/USANS Package: Set of tools for reducing SANS and USANS data. Requires the commercial IgorPro software.
- Citation: S.R. Kline "Reduction and Analysis of SANS and USANS Data using Igor Pro", J. Appl. Cryst. 2006, 39, 6, 895. doi:10.1107/S0021889806035059
- Nika: Conversion of 2D images into 1D for SAS. Requires commercial IgorPro software.
- Indra 2: Reduction of USAXS data. Requires the commerical IgorPro software. Written for the 15ID instrument at APS.
- DPDAK: Open-source Python tool for analyzing large sets of SAXS data. Works on Linux and Windows.
Data Modeling and Fitting
These packages can predict scattering curves for various possible nano- or molecular- structures. Some of the packages allow fitting of experimental data.
SAXS
- NCNR SANS/USANS Package: Can model form factors for many common object shapes in solution. Requires the commercial IgorPro software.
- Citation: S.R. Kline "Reduction and Analysis of SANS and USANS Data using Igor Pro", J. Appl. Cryst. 2006, 39, 6, 895. doi:10.1107/S0021889806035059
- Irena: Multiple tools for analyzing SAXS, SANS, USAXS, and USANS data. Allows modeling of diffuse scattering, form factors, reflectivity, etc. Requires the commercial IgorPro software.
- Scatter: Targeted towards analysis of transmission-mode SAXS and SANS. Allows modeling of nano- and meso-structrue materials (surfactants, lipids, micelles, vesicles, block-copolymers, etc.).
- Citation: S. Förster, L. Apostol and W. Bras "Scatter: software for the analysis of nano- and mesoscale small-angle scattering", J. Appl. Cryst. 2010, 43, 639. doi: 10.1107/S0021889810008289
