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 herehttp://surfer.nmr.mgh.harvard.edu/fswiki/CoordinateSystems?highlight=%28mni%29%7C%28coordinate%29.
I also wonder if what you are looking for can be answered by thishttps://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg54220.html past mailing list thread. Hope these notes help.
Cheers, Jocelyn ________________________________ From: freesurfer-bounces@nmr.mgh.harvard.edu freesurfer-bounces@nmr.mgh.harvard.edu on behalf of Hua, Jessica Jessica.Hua@ucsf.edu Sent: Monday, January 4, 2021 6:43 PM To: freesurfer@nmr.mgh.harvard.edu freesurfer@nmr.mgh.harvard.edu 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
