Dear Freesurfer Developers, 

I want to extract the entorhinal cortex from the original T1 image of my subect's MRI scans. Is there a way to do it; I used the the commands below to extract the CA1 subfield of the hippocampus. Is there a similar way to do the same for the entorhinal cortex? 

mri_extract_label lh.hippoSfLabels-T1.v10.FSvoxelSpace.mgz 206 leftCA1.mgz
mri_extract_label rh.hippoSfLabels-T1.v10.FSvoxelSpace.mgz 206 rightCA1.mgz

mri_mask orig.mgz leftCA1.mgz orig_left_CA1.mgz
mri_mask orig.mgz rightCA1.mgz orig_right_CA1.mgz

Many thanks,  

Stephanos
