Re: [Freesurfer] Compatibility of subcortical and cortical segmentations between Version 5.3 and 6.0

Hi Nils

no, in general we don't recommend this. It adds unneeded variance (and 
maybe bias).

cheers

[Freesurfer] Compatibility of subcortical and cortical segmentations between Version 5.3 and 6.0

2018-03-06 Thread Nils Opel
Hi Freesurfer Developers,

i am currently collecting structural imaging data from several large cohorts 
that have been processed using different freesurfer versions (5.3 and 6.0).

I would be interested on your experiences regarding compatibility between both 
versions for subcortical and cortical segmentations.

More specifically: would it be appropriate to include subcortical and cortical 
measures derived from both freesurfer versions (5.3 and 6.0) in the same 
analysis?

Thanks a lot in advance and best regards,
Nils
