Hi, RELION-3's re-implementation of the MotionCor2 algorithm masks hot pixels but ignores the defect file. Indeed this might bias the trajectory to the origin, but I would not worry as long as you run Bayesian Polishing afterwards; the convergence radius of Bayeisan Polishing is large. Bayesian Polishing compares particles with reference projections. Thus, the effect of fixed pattern noise is smaller than in reference-free methods.
