Other Details the final pool of particles was classified without alignment around the MPP cavity to separate the two orientations of Sub 9. the two classes were then refined, first globally and then focused on CIII, re-oriented along the C2 symmetry axis, to allow for subsequent 180 degrees flipping of one class and final re-pooled refinement with all particles having the same orientation of Sub 9
