Hi Karel,

This looks good to me. A local comparison of the 3dcalc-computed t to those output be 3dttest++ showed an exact match (using your exact expression with a change for DoF).

Note that if you are starting with volume #0 from 3dttest++, that will be an effect (beta) magnitude, not a z-score. 3dcalc will process all volumes using the same expression.
