Group analysis of inter-subject correlation

Hi Gang,
I recall that you mentioned earlier this year in an AFNI workshop that a new feature for group analysis of inter-subject correlation (results of 3dTcorrelation) would be available. I would like to check with you and see if this feature has already been distributed.

Specifically, I have several groups of subject (say patients and controls) scanned for many times (say visit_1 and visit_2); and I want to examine if the “inter-subject correlation” differs between groups, between visits, or if there is an interaction between these 2 factors, what’s your recommendation for this specific purpose?

Thank you so much!
