Yangyang,
A neurologic atlas is here: spm12_7219/tpm/labels_Neuromorphometrics.nii
and the definitions of the labels are in
spm12_7219/tpm/labels_Neuromorphometrics.xml
I use imcalc to separate out single ROI's. For instance, if I want
bilateral middle frontal gyrus, I use imcalc and enter the
labels_Neuromorphometrics.nii image with equation (i1==142) |
(i1==143).
Hope this helps!
Jim
