[Freesurfer] Fsaverage for ROI analysis of children

Hello all,

I have been conducting an ROI analysis and following the cortical thickness ROI tutorial found here: https://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness. After going through this tutorial with a few of my subjects I’ve noticed the ROI when registered to the fsaverage template is not in the correct position. I’m guessing this is due to the nature of my subjects (children ranging from 8months-11 years old). Is there a better template I should use for this analysis? Also, when I run mri_segstats to get the cortical thickness for my ROI, will these numbers be inaccurate too? Thanks in advance!

It is worth noting I am running Darwin-lion-stable-pub-v5.3.0

Best,

Michael S.
