[Freesurfer] Hippocampal Subsectioning

Hi, I was doing a hippocampal subsectioning https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfieldSegmentation on a data set. Previously recon-all -all was used, and then I did recon-all -hippo-subfields. I then used the script kvlQuantifyHippocampalSubfieldSegmentations.sh to find the volume of the hippocampus and its sub parts. I was confused as to the data I was getting out. The hippocampus seems to large. The voxel size is 0.5 mm * 0.5 mm * 0.5 mm so the hippocampal areas seem to large. Also the subunits of the hippocampus are larger than the actual hippocampus which again does not make sense. I attached one of the output files

Thank you for any replies, From Joshua Segaran
