1) 2D-average>iterative multireference alignment process (Boekema et al, 1986), using Ward's merging criterion until stable classes obtained; 2) 3D reconstruction> cylindrical symmetry was assumed and the final two dimensional projection converted to a three-dimensional map using an iterative back projection procedure (Frank, 1996).
