Hi all, I have just printed a cluster report (3dclust) from a conjunction analysis. The dataset contains only values 1, 2 or 3 representing 'above-threshold' activations for each of the two conditions (#s 1 & 2) and areas where they overlap (#3). My question is this: In the cluster report, I get centre of maxima coords as well as max intensity coords (they are different). Given my analysis approach I'm ok using centre of maxima coords but I wondered how 'max intensity' was calculated in afni given that all voxels in a cluster will have equal values (i.e. either 1, 2 or 3).

Any help would be most appreciated. Thanks.

Gary
