Hi Juergen,

If you ran recon-all -all, you should have a file called aseg.stats in your <subject>/stats directory. This will contain information (volume, intensity) from the automatic segmentation (aseg.mgz) for all the structures we label.

There are no surfaces generated for the hippocampus, so there is no thickness measure for that.

Dear Freesurfer users

I tried to compute the hippocampal volume with the following command:

mri_label_volume <volume> <label 17> <label 18>

but which is the most appropriate volume to label?

Is there also an opportunity to measure thickness and surface area of the hippocampi? I had run recon-all -all, but cannot find the results for the hippocampus in the file!

Thanks in advance Best regards Juergen
