Dear AFNI experts,

I have used other neuroimaging software package to preprocess ASL data and would like to use AFNI's 3dMVM for the group analysis. My question is that how can I create the mask for the group analysis. I have MNI space registered absolute CBF map and FreeSurfer processed T1 images for each participant. I would like to create the whole brain map (i.e., not just focusing on gray matter regions but gray matter plus white matter regions). Please advise.

Best,
JW
