Final maps were calculated from 2276 images from a total of 4500 from 10 individual datasets, with scaling in reciprocal space to crystallographic ribosome structures and correction for map anisotropy by B-factor weighting of amplitudes in XPLOR with respect to a similarly-treated control inactive ribosome. Selection of particles for inclusion in the final maps was by correlation coefficient with respect to the alignment model, designed to maximise nascent chain occupancy in the selected images.
