SUNBIM (supramolecular and submolecular nano‐ and biomaterials X‐ray imaging) is a suite of integrated programs which, through a user‐friendly graphical user interface, are optimized to perform the following: (i) q ‐scale calibration and two‐dimensional → one‐dimensional folding on small‐ and wide‐angle X‐ray scattering (SAXS/WAXS) and grazing‐incidence SAXS/WAXS (GISAXS/GIWAXS) data, also including possible eccentricity corrections for WAXS/GIWAXS data; (ii) background evaluation and subtraction, denoising, and deconvolution of the primary beam angular divergence on SAXS/GISAXS profiles; (iii) indexing of two‐dimensional GISAXS frames and extraction of one‐dimensional GISAXS profiles along specific cuts; (iv) scanning microscopy in absorption and SAXS contrast. The latter includes collection of transmission and SAXS data, respectively, in a mesh across a mm 2 area, organization of the as‐collected data into a single composite image of transmission values or two‐dimensional SAXS frames, analysis of the composed data to derive the absorption map and/or the spatial distribution, and orientation of nanoscale structures over the scanned area.
