You can extract a binary mask for any structure with mri_binarize --i aseg.mgz --match XX --o yourmask.mgh where XX is a number from $FREESURFER_HOME/FreeSurferColorLUT.txt (eg, 17 = left hippo) It is possible to generate hippo surfaces, but we cannot guarantee accuracy. Let me know if you want to know how. doug
