Abstract When biological samples are first exposed to electrons in cryo-electron microcopy (cryo-EM), proteins exhibit a rapid ‘burst’ phase of beam-induced motion that cannot be corrected with software. This lowers the quality initial frames, which least damaged by electrons. Hence, they commonly excluded or down-weighted during data processing, reducing undamaged signal and resolution reconst...
