Error downloading Liver CT sample image

Support
1

Hi guys
I’m using Slicer 5.2.2 and for some reason it cannot download Liver CT sample data which is built-in.
Does anybody know how I can download the sample data online?
regards

2

What is the error message in the Python console?

3

It says “failed to download from repository”.
I’ve downloaded previous versions(4.0.2 and 4.1) and tried to download the sample data and it was successful, but since I need Liver’s sample data which is only present in 5.0 and after versions, I have to somehow download it and load it into Slicer.

Please copy here the application log (menu: Help / Report a bug) for a bit more details. Thank you.

It seems that you are using a proxy server that does not let direct access to the server. You can specify proxy server for Python (see for example here).

If that doesn’t work then you can download from the displayed URL using your web browser and rename the downloaded file to liver.nrrd.

First time that I tried downloading the file, since it didn’t have a format assigned to it I gave up on it. But after I changed it’s name to liver.nrrd it worked!
