| == Description == Note: Despite the experimental tags, the 'phasecls' and 'fscls' almost always produce better results than the default linear variance classifier. Note that these options are mutually exclusive. |

| This is the main refinement command in EMAN. You should have your starting images in 'start.img' and your initial 3D model in threed.0a.mrc. The 'refine' command will then refine this model iteratively. Note that the 'total number of iterations' specifies the number of iterations the program will finish with. If 5 iterations have been run, then 'refine 8 ...' is run, the program will pick up after 5 iterations and run only 3 more cycles. If you want to start over again from the first iteration, you must remove all of the 'threed.?.mrc' files (except for 0a) and all of the 'classes.?.mrc' files. | '''GUI Programs''' ||[wiki:/Eman eman]||Image browser and tutorial interface|| ||[wiki:/Boxer boxer]||Manual particle picking|| ||[wiki:/CTFit ctfit]||CTF parameter determination and simulation|| ||[wiki:/V4 v4]||Viewing 3-D models in projection|| ||[wiki:/QSegment qsegment]||Interactive slice-by-slice 3D model segmentation|| ||[wiki:/QIndex qindex]||2D crystal preprocessing and evaluation|| ||[wiki:/HelixBoxer helixboxer]||Program for picking and evaluating non-square 'boxes'|| |

| Most of the options are simply passed through to other programs.
