External Email - Use Caution
Hi Sophie. No output is better than the other. If you have run all your
subjects with both, I'd say to take the average!

Subject: [Freesurfer] Mismatching hippocampal output
External Email - Use Caution
Dear FreeSurfer developers,
As I understand it is recommended data is processed using the same OS. However,
it also states on the FreeSurfer webpage that there is an exception for some
post-processing tools.
Recon-all was first done with:
FreeSurfer version: freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c
Platform: Darwin Kernel Version 17.4.0
Post-processing for hippocampal segmentation was done separately on two
different machines with different operating systems:
1) FreeSurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c
Platform: Linux Version 2.6.32-696.23.1.el6.x86_64
2) FreeSurfer version: freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c
Platform: Darwin Kernel Version 17.7.0
Both have slightly different volume outputs. Is this difference due to
software/OS differences? Which output would you recommend using?
I have attached recon-all logs in case they are of use for my inquest.
With thanks and kind regards,
Sophie
