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
