'mris_calc' is designed to perform be a simple "calculator" that performs a set of operations between two operands of the same type. These operands are either 3D structures (like volumes) or 1D arrays (like curvature files). You can add/subtract/multiply/divide/etc two operands.
How would you want to use 'mris_calc' on groups? When you say "mris_calc doesn't have a .log as output" do you mean you'd like to use mris_calc on two "log" files? Can you explain more what you are trying to do? Best -=R On 18/09/16 10:55, Nick Corriveau Lecavalier wrote: > > Hi Freesurfer team, > > > I have a 2 Group (MCI, CTL) x 2 (Time1, Time2) protocol.
