Hello AFNI experts,

I have a co-activation map with voxels that have different Z-score values. All I want to do is find the mean Z-score within that co-activation map. So, just a single number printed.

I have been investigating 3dcalc, 3dMean, and 3dTstat, but I don't seem to be getting what I want.

I am sure there is an easy way to get this statistic but I am drawing a blank!

Thanks!

Emily
