Hi Afni Experts,
As a follow up I switched groups A and B and also switched to AminusB. In this case I got group A >B which matches the raw data values. For some reason when I use BminusA and have groups BAnd A switched (effectively the same thing), the Tstat directionality is reversed of the raw data. Could this be a bug?

Thanks,
Ajay
