Dear Freesurfer experts,
we recently got access to a Linux-based cluster computer, and I need to run FreeSurfer pre-processing for several 100 subjects soon. We also have a Mac Pro with many cores that we used in the past and that could take part in the pre-processing.
I found an older reference which suggests you should not run the pre-processing for one study on different architectures/operating systems [1] because this may affect the results. Does this still apply to Freesurfer 6? What are your recommendations in this regard?
Also, out of curiosity: it is obvious why one should not use different Freesurfer versions, but what are the reasons for the reported differences between architectures/workstations?
