Good morning AFNI folks and thanks in advance for your help.

I'm looking to plot the bivariate between peak Z scores of connectivity obtained in my experiment, with a behavioral variable (in SPSS). Is there a way to extract only peak Z score, within an ROI, without taking the average? I've read through the -helpfiles for 3dmaskave and 3dmaskdump and don't quite see what I'm looking for (or, if its there, I've missed it!).

Thank you!
