Hi,
New user here! I’m trying to download the ModalityConverter extension: GitHub - ciroraggio/SlicerModalityConverter.
When trying via the extension manager, I got the following error message. So I went on extensions.slicer.org in order to do a manual installation (for Windows), but I can’t find the module. It’s supposed to be under the ‘Image Synthesis’ category, which isn’t present either. Did anyone experience a similar issue?
Thanks for the help!
Hello, thank you for writing. May I ask which version of 3D Slicer you are trying to download the extension from?
ModalityConverter can only be downloaded from the Extension Manager from version Slicer 5.9 onwards. I don’t understand what the error is, but it seems more like a download problem than an extension problem.
If you can’t find the extension with Slicer version higher than 5.9, then you can clone the repository and import it manually!
Let me know if you can do it, otherwise I’ll guide you step by step. 
I suspect the download failed because of Zscaler:
It’s an issue that affects me as well with my company issued computer.
