Downloading pretrained weights (~140MB) ...Error

[wang-bingh]

When I use ‘TractSeg -i hc1_DTI.nii.gz --raw_diffusion_input’ in Teminal to treat example DTI data, the following error continues to appear：

Loading weights from: /home/w/.tractseg/pretrained_weights_tract_segmentation_v3.npz

However，the ‘url: https://zenodo.org/record/3518348/files/best_weights_ep220.npz?download=1’ can open and download at Firefox Web Browser.

How to solve this problem?

Thank you.

Zenodo did a major update of their website and this also changed the way they accept download requests. I am working on a fix for this.

[wang-bingh]

I also tried "wget https://zenodo.org/record/3518348/files/best_weights_ep220.npz?download=1" in the Terminal, it can also download the Date(best_weights_ep220.npz). Should I change some code in a certain file of TractSeg? Or we will just have to wait for Zenodo to give us an responsein the future.

I fixed the problem and published a new version (v2.9) for pip.

[wang-bingh]

Thank you so much for your helpful suggestion! I re-installed the new version (v2.9) just that and it seems to work fine !

Hi Prof Jakob,
I am getting an error when I use Tractseg to treat non-HCP data and I am not sure what it is due to, any suggestions are well appreciated!
Thank you!

The code for Tract Orientation Maps that I am running is:
TractSeg -i tractseg_output/peaks.nii.gz -o tractseg_output --output_type TOM --super_resolution
