Wide-angle neutron scattering (WANS) is a powerful experimental technique to characterize atomic structures but has not been fully explored in biological molecules due to computational constraints. In this study, parallel Gaussian processes are shown to improve the computational efficiency of neutron scattering analysis algorithms sufficiently to enable the study of macromolecular biomolecules. A review of neutron scattering techniques and their ability to resolve macromolecular structure and function is also discussed.
