Hi Daniel,

Thank you very much.

Yes, I've referenced those links when I first started my conjunction analysis, and I found them very useful.

Here's my problem, though:

Using the suggestions in these and similar links, I can get the size of the total overlap. What I am not sure of is how to get the overlap for only one brain region out of the several that pop up during the conjunction analysis.

The way my data are now is that clusters for the main effect of A are labeled as "1", clusters for the main effect of B are labeled as "2", and the overlap regions are labeled as "3". So, my understanding was that if I use one of the suggested methods to pull info on the overlap, it is going to pull it for everything labeled as "3" as a whole. Am I wrong? Is there a way to specify that I want just one of the overlap regions? I apologize if this is clear in one of the message board postings or in the educational material/program help. I am just not finding the exact answer I'm looking for.
