Refine 3d Model

Classify by Projection

Once a reprojection of a model has been made, a set of particles may be classified with respect to  these reprojections.  Each particle image is compared with each reprojection (which therefore forms the original reference for each class). This comparison proceeds as follows: the ctf (phase modulation and envelope) of the particle is applied to the  reprojection that is involved. A quality factor for the match is then assigned between particle and appropriately modified reprojection. The particle is classified into that class associated with the reprojection with the highest quality factor match with the current particle.
