Hi Yolanda

does the resulting parcellation look ok? I think that's a small bug that may not have any effect on you (there will just be extra, unused color table entries)

Dear Freesurfer experts,

I have a question regarding mris_divide_parcellation. I have created a file containing the parcels from aparc.annot that I want to split and I have run the
following command. Why is Freesurfer allocating 36 additional units? When I open the new annotation file (rh.aparc.splitted) with matlab (using read_annotation), I
can see that at the end of colortable.struct_names there are a lot of parcels called "cluster38, cluster39, ..., cluster71". What are exactly these clusters?

Many thanks,
Yolanda
