Hi!
My 3d slicer version is 5.6.2 in Ubuntu24.04 and Windows11. I try to find Segment Comparison in two systems, but I can’t find it in the module. Could you taught me how to calculate Hausdorff Distance、Mean Distance or Dice Similarity Coefficient in 3d slicer? Thank you for your help.

After you install 3D Slicer, please install SlicerRT extension in the Extensions Manager. Segment Comparison module will show up then in the module list:

Thank you for your teaching. Great. I found extension in the module, but I couldn’t find SlicerRT. 3d slicer in Ubuntu couldn’t normally download. So I downloaded slicrrt in the slicerrt website and SegmentComparison packege of SlicerRT from Github. And then segmentcomparison path added by additional module path of modules in additional settings. After these steps, Windows11 show SegmentComparison in the module. But Ubuntu24.04 doesn’t have.

Your approach does not work with modules that have any C++ component. You will either need to build Slicer and SlicerRT from source code, or make sure the Extensions Manager can download the extension.

Do you have download problems only for SlicerRT or all the extensions? Are you behind a firewall (such as in hospital environment)? If so, then maybe that’s why. In that case you can download SlicerRT for 5.6.2 Ubuntu here:
https://slicer.cdash.org/build/3527219/files
You can install it using the “Install from file” button in the Extensions manager.

I am sorry. May you explain what is C++ component? Now I download SlicerRT from slicerrt website and install it in the Slicer.

And then I add segmentcomparison package from github in slicerrt. But I didn’t see segmentcomparison in the module.

Probably your organization interferes with your internet access (they use Zscaler or similar heuristic software that often breaks legitimate web applications).

Fortunately, there are alternative ways of downloading and installing Slicer extensions - see instructions here.

I sent an actual download link above. @Alice914 you can use that to download the zip.
