you could use fsfast to do it, but it might be doing some things you dont want. Eg, high-pass smoothing. PET images are usually acquired over hours and the high-pass filtering may remove stuff you want. Also, PET images are usually not spaced uniformly in time (should not matter if you're just doing correlations, but would mess up any temporal filtering).

Hi Freesurfers,
How can I perform seed based correlation analysis using PET images? In other words how can I use the same approach of FSFAST, but by including PET images instead of fmri images, to study the correlation between PET signal within a seed mask ( e.g precentral gyrus ) and the whole brain regions?
What is the best approach to run this analysis?
Best,
Mohamad
