By using "recon-all", I have parcellated an MR image and by using "mris_divide_parcellation" i have subdivided the result into specific regions,(each region has been divided into 10 subregions), the question I have is that are these subregions equal sized?

Are they equal sized within the whole cortex or within each region?

In other words,if i have 340 regions par hemisphere,are they all equal sized or not?
