Random Parcellation

1

Hi!

I’m working on building a whole-brain connectome, and I’ve been able to get as far as generating a tractogram. However, for my research, I need to generate a random cortical parcellation where each parcel is around 1 cm^2. From what I can tell Freesurfer doesn’t include such a parcellation.

Are there any publicly available tools or resources that can generate such a cortical parcellation or will I have to create this parcellation manually?

Thank very much in advance!

Maybe GitHub - miykael/parcellation_fragmenter: Fragments FreeSurfer parcellation annotation in N-equal sized parcels does what you need?

That looks like exactly what I need.

I’ll test it out and report back if it worked.

Thanks a lot!
