Hi Douglas, I've investigated the use of SAMSEG for AD/MCI patients. I'm using the 7.2 version of Freesurfer and I've realized that I get different results using the same data but when I run the SAMSEG multiple times (on the same patient).
Differently from using ASEG, SAMSEG provides also the chance to execute the code using multiple threads.
In the first run I've executed SAMSEG on ADNI patient id 002_S_0685 using the MP-RAGE series having ID I18211 (the link below provides the NIFTI version of the series which has been used for the processing). This patients is part of ADNI dataset.

The first execution of SAMSEG was with default settings (1 thread) and results are attached, the second was using --threads 6.
These results from the SAME series are similar but they are NOT the same.
How can we explain that?
