Hello. The attached code will also work. For all cluster max in the SPM results table it finds what the AAL and BA labels are from the MRICro maps. Just make sure you change the locations in the code for the BA and AAL maps.

I hope this helps,
Jason.

Dear Vincent,
One short answear.
You can take your results image (if that is the case) via the 'Save' button.
Then you can use MRIcron to watch the BA number, if your results image 
was in MNI space.
Best regards,
Juanjo

% Execute:
