Initial attempt at replicating in relion (parameters in next post). This is for Aca2-RNA, using a 100k subset of the 2D-classified particles (no prior 3D cleanup). A 1-class ab initio in relion, then local refinement in relion (1.8deg searches+blush) gives a nominally 3.3Å map; 3.5 Å w/out blush.

If your perception is that all interactions are transactional and that there is no such thing as sincerity of curiosity, or a desire to discover, then you will never value science. No matter how many economic arguments there are for funding it. Because you don’t understand the fundamental premise.
