Dear Marieke,
When you right click on a peak coordinates, it will display the
corresponding label for that given location in the atlas and a
subsequent menu will list the proportions of the intersecting regions
with a 10mm radius sphere centred around that location.
When you right click on a cluster size, it will list the proportions of
the intersection of the corresponding cluster with the regions defined
in the atlas.
Best regards,
Guillaume.
