Dear FreeSurfer experts,
i have created a ROI in qdec , where i have found a significant correlation between lgi and age.
I mapped this ROI to all subjects.
I am interested to compare in this ROI the pial-surface area, the grey matter volume and if possible the white matter volume for this specific region and i am not sure how to do this?
Best regards
Daniel Klein
For GM area and volume, you can use mris_anatomical_stats. See the recent thread on how. For the WM volume, how would you define the WM volume that corresponds to you label? We have a routine that parcellates WM based on closest proximity to a cortical label. doug

Dear Freesurfer experts,
have cortical thickness asymmetries ever been looked at using Destrieux parcellation scheme, either in adults or (even better) in children?
Thanks! Irene
not that I know of

We have mentioned this in: "Use of SVM Methods with Surface-Based Cortical and Volumetric Subcortical Measurements to Detect Alzheimer's Disease"
You can find the PDF in the FreeSurfer page: http://surfer.nmr.mgh.harvard.edu/ftp/articles/Oliveira_JAD2010.pdf
I don't have a good explanation though. --------------------------------------------------------------------- Pedro Paulo de Magalhães Oliveira Junior Netfilter & SpeedComm Telecom -- www.netfilter.com.br -- For mobile: http://itunes.apple.com/br/artist/netfilter/id365306441
