Hi there, i am using slicer in my lecture. I would be inetrested whether the extension BrainStructuresSegmenter is available or how i can use it.

Operating system: Windows
Slicer version:4.10; 4.10.2; 4.11 (nightly)
Expected behavior: Extnsion is abailable in the extension manager
Actual behavior: there is no such an extension. The linke is documebnted in version 4.10

Did you try contacting the authors of that extension directly? They may not be monitoring the forum. I don’t know if that extension is being maintained and it’s not registered to be built.
