Hi Doug
I use the MNI space! And what I do is the same with Ola, the following
is the exchange of massage, but I still can not know how to do? thanks!

Hi Doug,
Thank you for your response! I am still a bit confused about the vol2surf
command. I have a volumetric mask with voxels of interest based on a VBM
analysis in SPM. I would like to extract the cortical thickness measurements
based on these voxels. I am not clear what specifications I need to include
when using vol2surf. For example, what do I use as my registration matrix?Thank
you for your help!Ola

Make sure that your SPM volume is registered to the anatomical, then use
mri_vol2surf to map the volume to the surface, then mri_segstats to extract the
mean of the thickness

Dear FreeSurfer Experts,
I was wondering if anyone can advise on the best way to use an ROI mask created
in SPM (XjView) to extract cortical thickness values in freesurfer.
Thank you in advance for your help!

I don't know anything about XjView. You will need to be very specific and
detailed about what you did in order for us to help you. Eg, what space is the
ROI in?
