Hi Jessica,

FreeSurfer reports "Talairach MNI" coordinates which are MNI305 space. It may be helpful to take a look at our site which details FreeSurfer coordinate systems here.

I also wonder if what you are looking for can be answered by this past mailing list thread. Hope these notes help.

Cheers,

Jocelyn

Subject: [Freesurfer] Desikan Killiany Atlas Node Coordinates

External Email - Use Caution

Dear FreeSurfer,

I would like to conduct a network based statistical analysis. One of the inputs in the NBS toolbox is to provide a list of MNI coordinates for each of the brain regions in the parcellation. Is there an established list of MNI coordinates for the Desikan-Killiany atlas? And if not, do you know how I could identify the center MNI coordinate for each of the brain regions in this atlas?

Best,

Jessica
