Hi Koen and FreeSurfers:
I have a 3T dataset that has undergone processing using 5.1. I have also
run the Hippo sub fields command. Here are my results:
[root@NeuroImage-Gamma mri]# kvlQuantifyPosteriorProbabilityImages
$FREESURFER_HOME/data/GEMS/compressionLookupTable.txt posterior_right_*
posterior_Right-Hippocampus.mgz
volumeInVoxels:
right_CA1: 2473.34
right_CA2-3: 7530.08
right_CA4-DG: 4160.99
right_fimbria: 520.14
right_hippocampal_fissure: 376.772
right_presubiculum: 2780.65
right_subiculum: 4230.04
Right-Hippocampus: 2277.69
My question is : Since these are "subfields" of the Hippocampus, should
not the sum of all subregions be equal the volume of the Right Hippocampus?
Thanks so much!
