SAXSMoW (SAXS Molecular Weight) package is used for easy processing of small-angle X-ray scattering data from monodisperse systems (protein macromolecules, actually) in diluted solution. The package works with raw SAXS data (.dat files) measured on a relative scale. By default, the software tries to find best Guinier fitting and region of integration in Kratky plot, but experienced user can ajust the parameters by own hands and recalculate. More detailed description of the software you can find in our articles available by links in the bottom of this page. Here is input file example for Bovin Serum Albumin (BSA) taken from SASBDB.
