| -invert | Invert density in the image. |
| -rescale -0.1,5.2 | Rescale symmetrized data to average and standard deviation. |
| -axis 3,1 | Rotate to desired axis, with flag for alternate (requires -symmetry). |
| -handedness 1.4 | Check handedness above threshold (density is positive). |
| -check C,D,I | Check symmetry in correctly oriented map. |
| -find 1.5,2,1 | Find orientation: angle step, binning, and |
| flag to skip major axis (use with -symmetry). |
| -change C5,C6 | Change point group symmetry. |
| -Views | Output all symmetry-related views, (filename: out_??.img). |
| -asu 3 | Output a single or multi-level mask of asymmetric units (use with -symmetry). |
