Small-angle X-ray scattering (SAXS) in solution is a common low-resolution method which can efficiently complement high-resolution information obtained by crystallography or NMR. Sample monodispersity is key to reliable SAXS data interpretation and model building. Beamline setups with inline high-performance liquid chromatography (HPLC) are particularly useful for accurate profiling of heterogeneous samples. The program DATASW performs averaging of individual data frames from HPLC-SAXS experiment using a sliding window of a user-specified size, calculates overall parameters (I(0), Rg, Dmax and MW) and predicts the folding state (folded/unfolded) of the sample. Applications of DATASW are illustrated for several proteins with various oligomerization behaviors recorded at different beamlines.
