Re: [Freesurfer] SAMSEG and statistics

External Email - Use Caution

Hello,

this is true (i.e. reproducibility) for ASEG (when running recon-all -all).

But, if you use SAMSEG (i.e. running run_samseg instead) you get slightly different results everytime. This is regardless you use -threads flag or not.

My command line is (using the file I've provided in the link in my previous email):

run_samseg --input ./I18211_ADNI_12M4_TS_2_20060706103342_2.nii --output /usr/local/freesurfer/7.2.0/subjects/002_S_0685-I18211/SAMSEG_NIF

either using this version (1-thread) or a multi-thread

run_samseg --input ./I18211_ADNI_12M4_TS_2_20060706103342_2.nii --output /usr/local/freesurfer/7.2.0/subjects/002_S_0685-I18211/SAMSEG_NIF -threads 6

You get always slightly different results.
