Hi Freesurfer team,

I used Qdec to do my group analysis (MCI vs Control). I also analyzed fMRI data 
with SPM. My plan is to investigate functional activity where there are group 
differences in thickness. Is there a way to make a ROI using Qdec and to 
transfer it into SPM/MarsBar format (.mat) so I can get the functional beta 
values in this ROI?


I tried to make functional ROIs with MarsBar by taking the coordinates of the 
thickness clusters, but the size and shape of those ROIs are kind of arbitrary. 
Do you have anything to suggest?
