Dear Freesurfer Developers,
I’ve run the new longitudinal hippocampal subfields segmentation using Freesurfer’s developer version. Then I decided to extract stats for each hierarchy: HBT, FS60 and CA. I used the following command, for example:
mri_segstats —seg lh.hippoAmygLabels-T1.long.v20.CA.mgz —ctab-default —sum output.txt
I got what I wanted but decided to compare the results of one subject for Hippocampal_tail for each hierarchy and with the text file lh.hippoSfVolumes-T1.long.v20.txt. I got the following volume values:
lh.hippoSfVolumes-T1.long.v20.txt: 583.65 HBT: 593.4 FS60: 593.4 CA: 598.3
I wonder how do you actually extract stats that are present in lh.hippoSfVolumes-T1.long.v20.txt file? What is the reason for different values? I’m very curious since I cannot get the exact same stats as in the lh.hippoSfVolumes-T1.long.v20.txt file.
Thanks a lot! Donatas
