Extract the centroids from Buckner2011_17Networks atlas


#1

I intended to extract centroids of the atlas “Buckner2011_17Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz”

According to the post: https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2018-May/057046.html
I used the command as:
“”"
source_img_fname=${FREESURFER_HOME}"/average/Buckner_JNeurophysiol11_MNI152/Buckner2011_17Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz"

color_lut=${FREESURFER_HOME}"/average/Buckner_JNeurophysiol11_MNI152/Buckner2011_17Networks_ColorLUT.txt"

mri_segcentroids --i ${source_img_fname} --o ./Buckner2011_17Networks_centroid.txt --ctab ${color_lut}
“”"

I am wondering how to transform the volumetric 17Networks centroids to be embed into the surface-based fsaverage network centroids (scripts as https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2018-February/056056.html) ?

Any suggestions would be appreciated!
Thank you for your time!
