Hello Eugenio,

I am also encountering the same problem with negative subfield volumes obtained from longitudinal hippocampal subfields analysis using Freesurfer 6.0 on MAC osx.

I could not find the suggested solution for this problem. Could you please guide us on this issue?

Thank you for your time.

Best

Jay

Hi all,

I am currently running a longitudinal hippocampal subfields analysis using version 6.0.
Based on the visual inspection of images, I see that Freesurfer is doing a great job.

The problem is that I get negative values of the subfields volumes
e.g.
Hippocamap_tail -420.400366
subiculum -368.134590

The values seems to be reasonable, but why they are negative, i.e. why they have a '-' sign.
Could the minus sign be a hyphen?

Has anybody encounther this problem? I hope you can help

BW,
Chris
