[Region Move] Menu
Use [Region Move] to mirror regions across voxel axes, nudge them in 1-voxel steps, or drag them in the 3D view. Axis flips and single-voxel shifts modify the highlighted row in Assign Regions, or all checked regions when [Region Edit][Modify All Checked] is enabled.
Axis flips
| Menu item | Behavior |
|---|---|
Shortcut: Ctrl+7. Mirrors the highlighted region (or all checked regions when [Region Edit][Modify All Checked] is enabled) left–right across the X-axis center of the voxel grid. Undoable via [Regions][Undo]. |
|
Shortcut: Ctrl+8. Mirrors the highlighted region (or all checked regions) anterior–posterior across the Y-axis center of the voxel grid. Undoable via [Regions][Undo]. |
|
Shortcut: Ctrl+9. Mirrors the highlighted region (or all checked regions) superior–inferior across the Z-axis center of the voxel grid. Undoable via [Regions][Undo]. |
Axis shifts
| Menu item | Behavior |
|---|---|
Shortcut: Ctrl+1. Shifts the highlighted region (or all checked regions when [Region Edit][Modify All Checked] is enabled) by 1 voxel along +X (subject Left). Cannot be undone with [Regions][Undo]. |
|
Shortcut: Ctrl+2. Shifts the highlighted region (or all checked regions) by 1 voxel along -X (subject Right). Cannot be undone with [Regions][Undo]. |
|
Shortcut: Ctrl+3. Shifts the highlighted region (or all checked regions) by 1 voxel along +Y (subject Posterior). Cannot be undone with [Regions][Undo]. |
|
Shortcut: Ctrl+4. Shifts the highlighted region (or all checked regions) by 1 voxel along -Y (subject Anterior). Cannot be undone with [Regions][Undo]. |
|
Shortcut: Ctrl+5. Shifts the highlighted region (or all checked regions) by 1 voxel along +Z (subject Superior). Cannot be undone with [Regions][Undo]. |
|
Shortcut: Ctrl+6. Shifts the highlighted region (or all checked regions) by 1 voxel along -Z (subject Inferior). Cannot be undone with [Regions][Undo]. |
Interactive placement
| Menu item | Behavior |
|---|---|
| Shortcut: Ctrl+A. Enables a one-shot crosshair drag to move any visible checked region in whole-voxel steps parallel to the camera-facing slice plane, then restores normal camera control. Requires 3D region display and cannot be undone with [Regions][Undo]. |
Coordinate, undo, and 3D picking cautions
Flips mirror across the center of the voxel grid rather than the anatomical midline, and shifts step by 1 voxel in the region’s own image grid (not mm) without clipping out-of-bounds voxels until saved. Before pressing Ctrl+A, rotate the view or hide foreground slices so closer slices or 3D objects are not dragged instead, or right-click any 3D slice and choose Move Current Region Here to recenter the highlighted region.
