Below is the Thalamus ROIs I was referring to in the previous post.
I used Atlas>New atlas to import the subject specific atlases from the Freesurfer folder. I say "yes" when asked to apply the standard transformation Freesurfer-->Brainstrom. I tried to refuse to apply the standard transformation but it does not help.
Again, it works when I import the aseg atlas but not for any of the aparc atlases.
The goal is to define volume scouts to extract scout time series.
It seems that a part of the problem is that several ROIs are grouped together, see attached. Indeed when I import the Aparc atlas I only get 23 scouts when the atlas is supposed to include 68 of them.
1/The Thalamus ROI
2/One of the cortical ROI, with various regions that seem to be grouped together.
Thanks,
Thomas
