Hello all,
These new commands worked great for making individual grey matter masks! Thank you so much!
However, it gets a little tricky when combining them into making a group grey matter mask.
First, I averaged the masks together using 3dcalc. This looked pretty bad. Then, I simply added them, and that looked better, but a bit too inclusive. I am guessing this will probably be the best I can do since there is so much variability in an individual's anatomy. But I thought I would ask if anyone had any further suggestions for optimizing the mask?
Thanks again,
Emily
