Video tutorial overview

1: Initiating the workflow

1. Select the data object you would like to author an ROI for (Reconstructions or other ROIs are valid inputs)
2. In the author toolbar, select the ROI tool

2: Start Cropping & Aligning

1. After initiating the workflow, a new in-progress data object will be created. If you click into other tools, this will stay in the data tab so you can return to your work.
2. The viewer will default to X/Y slice views. You can cycle through these with the selector.
3. There are handles for rotation and cropping in the field of view. 

3: Toggling Elements & Submission

1. Through the process, it is helpful to turn on or off various visual elements. For example, turn off the rotation handles after nailing rotations to focus on cropping.
2. Once you are happy with the alignment & crop, submit the workflow.

4: Renaming

1. ROIs will nest under their reconstruction. By right-clicking on them, you can rename them for better labeling.
