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. _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
