Subject: [Freesurfer] negative values of hippocampal subfields volumes

        External Email - Use Caution        

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
