I tried running DeCA with the 3D Slicer 5-11-2026.01.02 release, but the module window opens like in the attachment, and the extension can’t be operated.
In the screenshot it looks like you are in the Data module. What happens when you try switching to one of the DeCA modules?
Sorry, I did not capture the right screen; here is a better one. When I switch to the DeCA module, I do not see the options to select the models and landmarks folders, thus can’t operate a DeCA atlas creation….
I can’t replicate this on my Mac with todays preview. Module shows and works fine:
There might be an issue with that specific build from that day. If you need to use it try with today’s preview, better yet use the stable (5.10).
If you encounter the issue with today’s preview as well, please share the full log file from that session.

With the last issue I can’t even load the module.
Here after a screen grab of the research display.
I copy here after the session.

[Qt] Populating font family aliases took 175 ms. Replace uses of missing font family “Courier” with one that exists to avoid this cost.
Extension is called DenseCorrespondenceAnalysis (not DeCA). Search for Dense and it should come up
Thank you, everything is going well.
Best.
