If you want the coordinates, you can also run mri_segcentroids on the aparc+aseg.mgz in fsaverage. Or, if you want them in mni152 space, you can run the 152 through recon-all and then run mri_segcentroids on the resulting aparc+aseg.mgz

It may be helpful to take a look at our site which details FreeSurfer coordinate systems here<http://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 this<https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg54220.html> past mailing list thread. Hope these notes help.

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?
