AttributeError: 'DynamicTraitedSpec' object has no attribute 'in_image'

[Michael Evans]

Hello,

I am receiving this error (below) when attempting to run the pet-volume pipeline and see there is a previous thread for this same issue. In this thread, the suggested solution was to use the dev version from github, as the issue was fixed with this pull request. 

This thread was a few months ago and I am using a newer version of Clinica, 0.10.1. I am wondering if this pull request fix was included in 0.10.1, or if I too would need to switch to the dev branch build?

I am using this setup on a shared HPC environment:

• clinica 0.10.1
• standalone SPM 12

Thanks so much,

Hello Michael, 

Thanks for reaching out ! This issue is addressed in next release, planned next week (hopefully if everything goes well). In the meantime you can use the dev version or just wait one more week, as you prefer. 

Also, we plan on dropping SPM12 totally and supporting SPM25 from next version (next week) onwards since SPM12 can no longer be publicly downloaded. There is a slight difference in the results but not noticeable. That would be true for our dev version also. SPM25 is very easily downloadable from their GitHub page, with the right MCR in the same software archive :-) 

Hope this helps,

Do not hesitate if you have further questions,

Alice
