Operating system: Mac  
Slicer version: 4.11.20200930  
Expected behavior: use “watershed” effect with segment editor extra effects extensions  
Actual behavior: segment editor

Hello! I´m a PhD student and I need to segment a teeth like you show me in the forum. But I cannot do it like you because I don’t have the tool watershed;so my results are unsatisfactory. How can I get your same tools with 3D slicer? Thank you for everything

Go to the “Extension Manager” → “Install Extensions” then search for “SegmentEditorExtra” with the right upper search textbox. Install and restart Slicer.

Thank you for your answer, but I can’t install them because they say me that I need an app to download. Do I need an specific program or app or similar? Thanks

It needs a dependency: MarkuptoModels extension. When you install the SegmentEditorExtra a notification appears asking to install the dependency.
