Hi Carissa – These are MNI coordinates. These mean paths are created only for visualizing group results. However the actual FA, etc measures that are used for group analyses are generated in each subject’s native space.

Best,

Subject: [Freesurfer] TRACULA -stat coord output file

Hello,

 

Are the contents of the *.coords.mean.txt file generated from the trac-all –stat command, the average MNI coordinates along the tract across subjects? Or average coordinates in native space?

 

Thanks!

 

Carissa
