Beam-induced crystal lattice reorientations match the few degree reorientations observed for single molecules in single particle cryoEM experiments , where beam-induced translation, rotation, warping and doming occur most dramatically within the first few e -/Å 2 of integrated flux . The lattice reorientations observed in MicroED experiments, and the visible motion of bend contours observed in imaging experiments, occurred most prominently within the same range of integrated flux values. We therefore anticipate that accounting for beam-induced reorientation during crystallographic data reduction will help improve the overall quality of MicroED data, as motion correction protocols have improved data quality for single particle cryo-EM. performed over all crystals of the type measured. For representative cases, the diffraction frame acquired after delivery of 2.45 e -/Å 2 fluence and rotation of 24.5 degrees, superimposed first with labels of predicted reflection positions determined by XDS without orientation refinements (magenta), and then with those determined with orientation refinements implemented (teal). Labels show all peaks whose centroids were calculated to be +/-1 degree of rotation from the displayed frame in each case (B,D,F).
