Dear SPM users,
 
I am trying to obtain mean signal intensities of some portions of brain. Therefore, I hope to mask normalized images (normalized on T1 template in SPM) as:
right frontal,
left frontal,
right occipital
left occipital lobes.
 
Is there any way to generate those images by using SPM or any software?
I would appreciate any helps.
