Dear SPMers,

In my data analysis, we have two groups (let's say Groups A & B), and I have two Tasks (tasks X & Y).
Using conjunction analysis, I have observed brain regions common to task X & Y in Group A, but not common activation in Group B.
I wonder how can I do a two-sample test on the conjunction result to show that result is statistically significant between the two groups?

Thank you very much for your time!
