Hello, 

I'm comparing 2 independent meta-analysis on MRIcroGL. I can assign the activations from each independent meta-analysis different colours (e.g. blue, red) to compare the activations, but it's difficult to see their overlapping activations accurately. How can I assign the overlapping activations from both meta-analysis a third colour (e.g. green) so that I can visualise the activation commonalities between the two independent studies?

Such that I would be able to visualise (i) areas that show unique activations from the 2 meta-analyses in blue and red (i.e. no shared activation across meta-analyses), and (ii) common overlapping areas activated across both meta-analyses in green.

If I cannot to do this on MRIcroGL, can this be done on MRIcron? 

Thank you in advance!
