Hi all, I want to extract cortical thickness for a ROI (dlpfc) which was defined in volume space. I search it in Freesurfer Wiki and find the description in website (http://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness). But, in the second, it said it need an T1 volume (average of subjects) which was called TT_avg152T1.nii. How can I calculate it? What is the voxels of ROI and T1.nii, 1*1*1 mm2?
Thank you

Hi Wang
what volume space is it defined in? Generally you can use mri_label2label with the --paint option to sample a label onto a surface.
