Schematic diagram of SAXS-related routines in Situs 2.5. Visualization and modeling of atomic structures into SAXS bead models are supported through a conversion into 3D volumes representing the beads using the pdb2vol kernel convolution tool. Docking between atomic structures and 3D maps can be achieved through a number of approaches (see text). The data can be prepared further for the visualization using a variety of analysis and editing tools. Optional Gaussian kernel convolution with pdb2vol facilitates the smoothing of bead surfaces for their visualization in the form of density isocontours
