External Email - Use Caution Dear Thomas,
Thanks for your response. I have one more question here: I was looking at the Schaefer parcellation paper where authors have 100, 200, 300, 500...1000 areas parcellation. Is there a way to choose among these parcellations (i.e., what's the basic difference/justification/significance of each of these parcellations over one another) for cortical structure analysis? Thanks!
