Issue summary

Hi there, I am rerunning my code and since last update annot_to_gifti stopped working. Something about unable to read giftis even if I give it annot's. Appreciate your help! Thanks again Lauri

Hi @ltuominen. This appears to be caused by a recent PR in nibabel. We're currently fixing this. We even have the PR ready. I was actually working on this at this exact moment. We'll merge it in a couple of minutes max. I'll let you know when the PR is merged :smile:

[ltuominen]

Wow! This is the speed I like to see things happening.

[VinceBaz]

The PR is merged @ltuominen. Let us know if the bug is fixed with the new version :smile:

[ltuominen]

Works perfectly! Thanks again

[VinceBaz]

Awesome!

I am having the same issue, even if I am using the latest versions of neuromaps (0.0.4) and nibabel (5.2.0). Would you have any tips on how to solve it? @VinceBaz

Hi @Turius, we should have fixed the issue on the main branch, but we have not released an official new version on pypi yet. Could you please update the package to install from the latest github version?

To confirm, if you run the following code, the output should be something like 0.0.4+51.gefef838 instead of just 0.0.4.

python -c 'import sys,neuromaps; print(sys.version); print(neuromaps.__version__)'
