It doesn't make sense to me why the T1.mgz isn't seen although it is in the folder.?
No, it doesn't make sense.
Yes I confirm that this is indeed the error message I get
Just to make sure I replicate this exactly:
- On a Windows computer, you untar the file you just sent me with 7-zip
- In Brainstorm, you create a new subject
- Right-click on the anatomy folder of the subject > Import anatomy folder > Select file format "FreeSurfer folder" and select top-level folder "SavBen1" (and not any of its subfolders)
