I'm running into a problem when subparcellating my regions of interest where after subparcellating there are some sublcusters that are labelled identically by freesurfer even though they are distinct subclusters. More specifically, I ran one iteration of mris_divide_parcellation passing it 400mm subclustering size and then ran a second iteration passing it 200mm (I did this because I want subclusters that are square-ish in shape as opposed to long bands). On the first iteration there is no problem, the second iteration however produces the problem I described where distinct subclusters are considered to be the same by freesurfer. I have attached a picture of exactly the problem since this explanation is a little convoluted. 

Any help would be greatly appreciated.

Thank you,
