WebFinally, one may choose to calculate density using either cryoEM or X-ray scattering factors. At low resolution, this probably makes little difference, but might at resolutions better than about 3.5Å. The default is to use X-ray scattering factors; to turn on cryoEM scattering factors instead, use the following flag:-edensity::cryoem_scatterers WebApr 26, 2024 · As an integral part of the cryoEM structure determination process, computational tools have been developed to build atomic models directly from a density map without structural templates. Nearly a decade ago, we created Pathwalking, a tool for de novo modeling of protein structure in near-atomic resolution cryoEM density maps.
