CRYSOL is a program for evaluating the solution scattering from macromolecules with known atomic structure and fitting it to experimental scattering curves from small angle X-ray scattering (SAXS). As an input one can use a PDB file with an X-ray or NMR structure of a protein or a protein-DNA(RNA) complex.

CRYSOL 3.0 evaluates the hydration shell and its scattering in a different way: instead of using an envelope function, CRYSOL 3.0 "incrusts" the surfaces and interiors (were possible) of atomic structure with the dummy water beads. This way of the shell representation is more suitable for macromolecules with complex non-globular shapes and/or with cavities.
