Thanks, Bruce. That might be a bit of a dead end since it sounds fairly involved to write a spherical partitioning scheme to a .ic file. Is there a good way to tessellate a surface with nearly-equal area labels using any other FreeSurfer tools? Thanks again!

Hi Andrew,
these are icosahedral supertessellations, which come in fixed increments. I guess if you generated some other partitioning of the sphere and saved it in .ic format it would work, but you'd have to write your own.
cheers Bruce

Hi!
I'm trying to partition a surface into a number of random but roughly-equally sized areas, and I've been using the "mris_make_face_parcellation" function to do this. Is it possible to have a finer control over the sizes of each label it generates? I only see 7 options in: $FREESURFER_HOME/lib/bem/ic[1-7].tri (as per the program usage). Can I specify custom ic*.tri files (and also, how would those be generated)? I've tried mris_divide_parcellation, but that only makes strips which aren't necessarily the same area. Thank you!
Best Regards,
Andrew
