EMAN

Refine 3d Model

Align and Average Particles

Particles are aligned in a succession of steps. The first two particles are aligned to each other (using standard techniques); the third is then aligned to the average of the first two. Subsequent particles are thereafter always aligned to averages of the prior particles.

  A file classums.img is created by this round (which  the refine command will rename to a file like classums.1.img). The Euler angles are assigned to the class sums and written to the headers. These Euler angles are identical to the Eulers from the original reference projections.
