Hi Yue
if you sample them on to the surface with mri_vol2surf you can use the
overlay histogram facility in tksurfer to do what you want. You can also
use mask_label to remove values outside of an ROI if that is what you are
interested in.

Hi All,
I have T1-weighted MPRAGE images and I run recon-all to generate surfaces
and labels in freesurfer. Then I would like to do statistical analysis in
the regions I am interested in. For example, I would like to generate a
histogram of intensities in frontal cortex or in occipital. I can display
these regions in different color in freeview based on the look-up table but
I don't know how to use them to generate histograms in freesurfer or create
binary masks then I can do the analysis with these masks in matlab.
I use freesurfer to do this because I see these beautiful color
segmentations. It would be really painful to manually create regional masks
for a group study. I am new to freesurfer and I really appreciate if someone
can point out a direction.
Thanks!
Best,
Yue
