Abstract
There is provided systems and methods for determining variability of cryo-EM protein structures from a set of cryo-electron microscope images. The method includes: performing iterative optimization, each optimization iteration including: determining the updated variability coordinates for individual images from the set of images using a current value of the variability components; determining the updated variability components for multiple images of the set of images, using the updated value of the variability coordinates, by solving a set of linear equations, the linear equations comprising a sum of weighted compositions of projection and back-projection operators, the equations are solved by arranging the equations into a block-diagonal matrix form.
