MRI, volume Desikan-Killany atlas

[AishwaryaGK]

Kindly seeking an guidance on downloading the volumetric analysis of the brain mri in Desikan – killany atlas form.
I am able to find the Desikan – killany atlas under tess_cortex_central_high but, unfortunately I am unable to download the exact volumetric file.

If you segmented your MRI with FreeSurfer the Desikan-Killiany atlas is already there as an anatomical volume atlas.

Check this post:

Volume based Destrieux atlas

Sorry for the response delay. No, there is no easy solution to convert between surface and volume atlases. But, there are already available in FreeSurfer. After processing your MRI with FreeSurfer, you have access to the Desikan-Killiany (aparc+aseg.mgz) and Destrieux (aparc.a2009s+aseg.mgz) atlases as volumes: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI
