SAXSutilities (BHplot, DataTools, EDFplot, EDFtools, ASAXS) are Matlab based graphical user interfaces which have been developed for the online processing and analysis of Small Angle (X-ray) Scattering data. They are grouped in the package SAXSutilities which is available in a compiled version (not requiring a Matlab licence) for Windows and Linux (Mac is currently not supported)
