[MarcelRosier]

the open in collab button opens the aurora repo notebook, links can be generated here

[neuronflow]

Yes, is there a way to autogenerate links?

Yes, is there a way to autogenerate links?

maybe, but i dont think it's needed since it's justing modifying a single line, would not over engineer this.

@evamariie can you please try to fix this?

Hi, I checked the colab link for BraTS Toolkit, for me it points to https://colab.research.google.com/github/BrainLesion/tutorials/blob/main/BraTS-Toolkit/glioma_segmentation_with_BraTS_Toolkit.ipynb

I fixed the wrong link in preprocessing, see #48
