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!

Hello AFNI experts,
I have two z-scored co-activation maps. I would like to compare the spatial overlap between these two maps by computing the Dice Coefficient.
The first step in preparation of doing this, is that I need to threshold and binarize the two co-activation maps.
The co-activation maps consist of both positive Z-scores (activations) and negative Z-scores (deactivations).

Hi all,
I was wondering if anyone knew of an openly available co-activation pattern analysis (CAPS) pipeline? I am very interested in conducting this analysis on some resting state data I have and was just curious if anyone knew of something available.
Thanks!
Emily
