Hi,

I'm brand new to neuosynth. I asked a question yesterday, but I think I've figured out a way to ask it "better."

I'm interested in using the map that neurosynth creates for theory of mind ("theory mind"). If I want to mask each of the regions in that map- how do I get at each of them individually? I've been able to find a handful of papers that seem to look at several main regions pulled from this map. But I can't figure out how the regions of interest are being defined.  I can use the entire file as a mask - but then I just get one output value of activity for ALL the regions in the mask - not each of the large ones separately. 

I really hope this makes sense.
Thanks!

Hey Sarah,

If you are a matlab /SPM user you can look into this I think: https://en.wikibooks.org/wiki/SPM/How-to#How_to_remove_clusters_under_a_certain_size_in_a_binary_mask?

Hope it helps

Remi
