Anton Paar's SAXSanalysis software for processing and analysis of small-angle X-ray scattering data, combining automated data reduction with analysis routines that yield Rg, the pair-distance distribution p(r), particle size, the Porod constant, specific …

Data-collection and reduction software for Rigaku BioSAXS laboratory instruments, with some built-in analysis and an optional add-on module for more advanced analysis. It controls measurements and reduces 2D detector data to 1D scattering curves.

Anton Paar's SAXSquant software controls their SAXS instruments (such as SAXSess and SAXSpoint) and processes large scattering data sets using customisable templates for measurement and reduction. Legacy instrument-control software; see also SAXSanalysis.

A package by Michael Sztucki (ESRF) for on-line processing and analysis of SAXS data, handling 2D EDF detector images through to 1D profiles. It provides beam-centre finding, masking, azimuthal regrouping and display, and was rewritten in Python 3 in 2019…

An open-source toolkit for viewing and converting small-angle scattering data, built on the libsaxsdocument and libsaxsimage libraries. It reads, converts and displays a wide range of 1D and 2D SAXS file and image formats, and is commonly used as a lightw…
