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?
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.
