Hi Lena
you could use mris_anatomical_stats -l <path to your ROI> on each subject
to extract the average thickness on each then do the statistical comparison
on that list of numbers.

Thanks, Bruce. I ran the recon-all for all subjects before and then did the
group analysis using the mri-glmfit command and qdec. Sorry, I don’t quite
understand. What exact command do I use?
Mri_label2label --srcsubject fsaverage --srclabel fsaverage/label/(spm roi
image file names?) --trgsubject PAC01 PAC02 PAC03…PAC70 –trglabel PAC01
PAC02.. PAC70/label/(spm roi image file names?) --hemi lh –regmethod
surface
How do I next do the group comparison on the ROI?
Many thanks again,
Lena

Hi Lena
Sure, but you will need to run all your subjects through recon-all first.
The if the ROI is in MNI space you can use mri_label2label to map it to our
group space fsaverage.

Sorry, I haven’t heard any replies so am re-posting this again
for help please:
Dear Experts,
I have 3 groups: A, PC, HC
I did a VBM analysis in SPM and found group differences in grey
matter volume in 2 clusters:
1) Bilateral pre-/SMA, left middle/superior frontal gryi
2) left inferior/middle temporal/fusiform/inferior/middle
occipital gyri/superior/inferior posterior cerebellar lobe
Is there any way I can use the SPM images to extract these ROI
regions to see if they differ in cortical thickness and surface
area please?
Many thanks,
Lena
