| Save Region | Saves the current region(s) to a file. | run save_region |
| Save All Regions | Saves all regions as 4D NIfTI files. | run save_all_regions_as_4d_nifti |
| Statistics | Exports region-based metrics to a text file. | run region_statistics |
| Check All Regions | Checks all regions in the list. | run check_all_regions |
| Uncheck All Regions | Unchecks all regions in the list. | run uncheck_all_regions |

The following functions modify regions:
- Flip: X, Y, or Z axis.
- Shift: positive or negative shifts along X, Y, or Z.
- Morphological operations: Erode, Dilate, Smooth, and Defragment.
