Did you make the from the ?h.aparc.annot of fsaverage? If so, why not
make the label from the ?h.aparc.annot from the individual subject and
then calculate the thickness from that?

Hi Doug,
We are trying to look at the cortical thickness of a few different
ROIs (primary auditory cortex) and see how these areas relate to the
EEG ERPs we collected on these subjects as a function of age and
development. I created the ROIs using the mri_annotation2label
command per hemisphere then mri_label2vol to create a binary volume
file for each ROI in each hemisphere. Does that sound correct or
would you recommend doing it a different way?
Best,

Subject: Re: [Freesurfer] Fsaverage for ROI analysis of children
Can you back up and tell us what it is you are trying to do? Where did
the ROI come from and how did you create it?

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.
