Regionprops does not distinguish left and right hemisphere in Julich-Brain 2.5
When retrieving region properties of FP1, the values for left and right hemisphere are identical:
atlas.select_region('fp1')
for props in atlas.regionprops(space).values():
print(props)
will return
Region properties of "Area Fp1 (FPole) - left hemisphere"
centroid_mm [-2.28788811 65.01471329 -3.02237762]
volume_mm 17875.0
surface_mm 7721.644177125269
is_cortical True

centroid_mm [-2.28788811 65.01471329 -3.02237762]
volume_mm 17875.0
surface_mm 7721.644177125269
is_cortical True
Expected: significantly different centroids, slightly different area and surface
