Hi Doug, I tried to pick up from the thread below to get MNI coordinates of each destrieux parcellation region.

https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2013-July/032037.html

I created label files from

mri_annotation2label --subject fsaverage --hemi lh(/rh) --annotation aparc.a2009s --outdir label_destrieux # which works fine

And I tried to get the coordinates of each labels using

mri_surfcluster --in ~/subjects/fsaverage/surf/lh.thickness --clabel 
<label file> --sum <output file> --centroid --thmin 0 
--hemi lh --subject fsaverage

But, all left labels would produce the same coordinates and so does right labels. (I've attached few example files here with). Also, it says TalX, TalY, TalZ are these coordinates in MNI or Talairach?

Thanks for help.
