I see. You will need to sample it onto the surface before you can use
mris_divide_parcellation.

Dear Bruce
The parcellation I have is not on surface, it is volumetric.
I wanna increase the number of its ROIs, I thought maybe I can change it
into an annotation file and then use "mris_divide_parcellation".
Hope it is clear enough now.
Best
Maedeh
