You have to run recon-all through to the end. You can then extract a GM
mask from that. You will need to register your PET image to the
anatomical (mri_coreg), map the PET into the anatomical space, then use
mri_segstats to compute the mean PET in the GM mask. Alternatively, you
may want to use
Hello FS team,
I am new to FS and using version 5.3 on a Mac. I have minimal programming
background and this might be a very easy question, however I was not able to
find a similar one in the archive.
I have T1 MRI images from multiple subjects and I need to extract the brain
gray matter mas
Hi Emily,
is it a volume or surface functional map? If volume, I think it should be
pretty straightforward to sample it onto the surface with mri_vol2surf
then go from there. There is probably a way to do this in SUMA also.
cheers,
Bruce

Dear Group,
Back in April, Anil Roy posted a question about methods to generate a gray
matter mask that can be fed into AFNI . . . I'm wondering if the opposite
can be done? Can a functional mask made in AFNI be fed easily into
Freesurfer? Currently this mask is saved as a NIFTI dataset.
Thank
Do you mean cortical masks? If so, then {lh,rh}.ribbon.mgz are binary
masks. You can convert them to nifti with:
mri_convert lh.ribbon.mgz lh.ribbon.nii

Hello all,
Is there a method to generate a gray matter mask in Freesurfer that can be
fed into AFNI. Could you please point me to any existing documentation on
the FS wiki that already does this as I was unable to find anything.
Thanks a lot,
Anil.
