Hi,
I wonder if someone can help me to do something similar to that:
" the mean intensity of each FreeSurfer region (ROI) for the 45
subcortical and the 68 cortical regions were assessed the mean intensity of
each FreeSurfer region (ROI) for the 45 su
glad I was of some help. I still need my questions answered.

Hi,
I already used VMware as virtual machine to install Freesurfer, I would
advice you to change your OS to linux or Mac , it won't take the same time

the freesurfer and use tar c

I have a nifty MRI, converted to mni 305 space when I apply recon-all, I

I used freesurfer for ADNI data, specifically MRI for AD/CN. Even I run
segmentation many times , I always having the same statistics. Would you
share with us the commend line you used !

Firstly, thanks for your explanation, I didn't know that it would take less
than hours since I used recon-all to run 202 samples, I used parallel to
