BL4-2 Software Overview


There are several computer programs for data acquisition, analysis and visualization available to the users at the BL4-2 beamline. Several of these programs have been developed and are maintained by the BioSAXS group at SSRL. They are mostly integrated into the general data aquisition system at the Beamline 4-2. As open source software the source code for these programs is available upon request (please contact the BL4-2 staff). Several other programs that are available at the beamline for data analysis and visualization that have been developed elsewhere.  The following tables give and overview of the available software:
