Hi,  
I drew a rectangle ROI box in slicer, and want to change it to a label map. Then I can get a mask. What should I do?

Check the ‘[Markups to surface](https://gitlab.com/chir-set/Tools7/-/tree/master/MarkupsToSurface/)’ module. It can create a segment from an ROI, that you can convert to a label map in the ‘Data’ module.
