Hi Chris,
hmmm, didn't realize that it broke with that many faces. You could try mris_make_face_parcellation.

Hello,
I've been through the threads and can't find the answer to this one.
Problem:
- Subdivide the cortex into 5000++ (ideally>10,000) units per hemisphere
I've tried using mris_divide_parcellation but unfortunately it got very upset trying to find a "unique rgb colour" after I had managed to achieve >2700 new labels (also I was not entirely sure how to transfer these annot labels to the annot.mgz but that's a side issue):
CTABfindRGBi: rgb was invalid CTABfindRGBi: rgb was invalid CTABfindRGBi: rgb was invalid .. etc.,
I'm not really bothered about visualising the result per se, I just want each small area_ through _the cortical mantel to be assigned an unique value (like in the annot.2009s.mgz images but with many many more areas) so I can then convert to nifti and run numerous MATLAB scripts across multiple coregistered scans. Is this approach going to work??
Cheers,
- Chris
