Hi Antonella, The volume given by the hippocampal subfield tool is in .5x.5x.5 voxels. Therefore, to convert to cubic millimeters, you need to divide by 8. Regarding the sufield <-> A/P question, the only correpondance is "Left-Hippocampus" <-> left tail and "Right-Hippocampus"<->right tail Cheers, /Eugenio
