Hi everyone,
I would like to use CAT12 in order to perform ROIs analysis of PET data.
Recently, I read this thread (https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind1807&L=spm&P=R51199&1=spm&9=A&J=on&d=No+Match%3BMatch%3BMatches&z=4) in which Christian Gaser suggested two different method to use cat12 for PET data. However, the original poster of that question wanted to perform voxel-wise analysis on its PET data. On the other hand, i would like to extract FDG values (in subject space) from the set of ROIs present in the atlases that CAT uses.
The idea is to linearly register T1 and PET images, than, if this is possible, using CAT to extract the values not only GM and WM values, but also FDG ones. If there is no automatic way of doing this, I still reasoned that at a certain point, CAT must register its atlases to the T1 images, since to my understanding the ROIs values extraction is done in the subject space. Is it possible to access this registration and use them for FDG values extraction ?
Thanks in advance for any suggestion
Best
Alain
