Hi, I am having a issue of launching the extension “segmentationwizard” in 3d slicer version 4.11.20210226.

It can not be found in the drop down list and show “SegmentationWizard module is not loaded” after I manually search in the search field.

Hoping someone can help me resolve this issue.  
Thanks in advance!

The extension is not maintained anymore - see this [bug](https://github.com/QTIM-Lab/SlicerSegmentationWizard/issues/1) unresolved for over two years. Since SegmentationWizard extension just made Slicer core features available with a somewhat simplified user interface, you don’t need to use it.

You can learn more about Slicer’s segmentation features [here](https://slicer.readthedocs.io/en/latest/user_guide/image_segmentation.html). If you tell more about your segmentation task then we can provide more specific help.
