Hi Freesurfer folks,

I was wondering if anyone knew an automated or semi-automated method for calculating radial distance along the longitudinal axis of the hippocampus from a surface generated by tessellating the segmentation from aseg.

I know radial distance is used to examine local changes in morphology in cases such as aging and dementia - I was curious if there anyone has done so using the freesurfer Hipp segmentation as the starting point.

Thanks so much! Jared
