The 5 alignment parameters (2 for center and 3 for orientation) were searched simultaneously for each particle image. The search is executed by a new optimizaiton algorithm, multi-path simulated annealing, based on Cross Common Lines. There were 4200 good particles discriminated from 4865 raw particles by a Consistency Criterion. The best 81 particles were empirically selected by a double threshold method from the 4200 good particles. The map's resolution was measured against the Known X-ray structure (PDB ID: 1UF2).
