Hi,

I have three questions about the transformation.

(1) Is Desikan-Killiany Atlas in Talairach space? The volume was transposed onto the "inflated" cortical surface based on the image in freesurfer/average/mni305.cor.mgz ?

(2) DK_atlas seems to be obtained from the inflation of interface of gray and white matter. Did you release the inflated surfaces based on the inner and outer surfaces ?

(3)  I have transformed this atlas from surface to volume using mri_aparc2aseg with default parameters (e.g. mri_aparc2aseg --s bert). Is this transformed volume in Talariach space ? Do I need transform it to MNI space again ?

I am looking forward to your reply. Thank you very much !

Best Wishes,

Zhiqiang Sha
