Re: [Freesurfer] Custom brain segmentation to equal sized regions
I don't think this will do it, and I don't think we have anything that will do this precisely. You can do something like it by running the xhemi stream http://surfer.nmr.mgh.harvard.edu/fswiki/Xhemi, mapping the lh and rh thickness to the lh for fsaverage_sym, then run the face parcellation on fsaverage_sym On 3/21/17 2:20 PM, Bruce Fischl wrote: > Hi David > > mris_make_face_parcellation can do what you want for the cortex.

Re: [Freesurfer] Custom brain segmentation to equal sized regions
Hi David mris_make_face_parcellation can do what you want for the cortex. If you use the sphere used for cross-hemisphere registration as input I think (Hopefully Doug can tell us what it is called) cheers Bruce On Tue, 21 Mar 2017, david.kam...@pet.wayne.edu wrote: > Freesurfers, > > Is there a way to segment each hemisphere to an identical number of equal > sized regions which are as close in size and location as possible to their > contralateral homotopic regions. > Eg.

[Freesurfer] Custom brain segmentation to equal sized regions
Freesurfers, Is there a way to segment each hemisphere to an identical number of equal sized regions which are as close in size and location as possible to their contralateral homotopic regions. Eg. Id like to segment the left hemisphere to regions with a 2 cm2 surface and do the same for the right in order to compare asymmetries in these small regions. Anybody had done this before?
