[Freesurfer] Hippocampus volume calculations

Hi, I am calculating hippocampus volumes with 5.2 in CentOS 4.

I compare volumes (the same apply for lh and for rh) when calculating as:

Left.Hippocampus value in 1mm3 from aseg.stats I use the method kvlQuantifyHippocampalSubfieldSegmentations.sh and

obtain the nonPartialVolumeStatsLeft.txt, divide each value by 8 in order to get mm3, and sum every column except left_hippocampal_fissure.

I obtain quite different values, for example: row.names lh.aseg lhHIP rh.aseg rhHIP 1S_00 4848.83828.187 4878.83767.7392 S_02 4153.83371.517 4547.63389.918 Am I doing anything wrong? Should I calculate the hippos subfields volumes differently?

Many thanks! Gari
