| <infile> | Set of images to be averaged |
| <outfile> | Output, 1 image will be appended |
| [res=<in A>] | Resolution in A if structure factor is not used |
| [sffile=<file>] | Structure factor file used to fit data in infile |
| [mask=<rad>] | Circular mask |
| [copyeuler] | Used only if the filspec is cls####, will read the Eulers from proj.hed |
| [refmask] | Only for cls#### files, will mask based on proj.hed |
| [ref0] | Will ignore the first image in the file |
| [copyrefs] | Copy proj.hed image into the output file |
| [even|odd] | Uses only even or odd numbered particles |
| [snrmult=<val>] | Multiply the SNR by this number when Wiener filtering |
| [nolog] | Do not log a record of this program in .emanlog |
