Hi again, like I said in my previous emails, the measurements from the subfield tools are based on .5x.5x.5 voxels, so you have to divide them by 8 to convert them to cubic milliliters. Then, if you add up the volumes from the subfields (without including the hippocampal fissure), you should get something close to the measurement based on aseg.mgz (2166). Kind regards, Eugenio
