Hi,
Just following up on my previous email (see below) as I have not yet heard back. I also have another question regarding the lh.wm.mgh and rh.wm.mgh generated by pctsurfcon. How do I view these as surface overlays on T1 brain scans? Thank you very much. ________________________________ From: Sabrina Yu Sent: Thursday, December 10, 2015 2:47 PM To: Freesurfer support list Subject: Gray matter intensity Hello, I have been following the instructions in this email thread: https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2014-April/037240.html.<https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2014-April/037240.html> And have successfully gotten the wm-gm signal intensity contrast, but now have a few questions regarding signal intensity for white matter and gray matter intensity. 1) Does the wmparc.stats contain mean white matter intensity values for each ROI? 2) Is it possible to extract these same mean intensity values for gray matter? There is no gmparc.stats file. We know that it's possible to calculate these from the WM/GM ratio from pctsurfcon, but it'd be great if there was a more direct way to get this data. Thank you, Sabrina Yu
