Hi FreeSurfer,
I ran the trac-all -stat command on some of my participants, and I noticed that some of the values that were outputted contained NaN. Why are the values coming out as NaN?

Those values are at the endpoints of the tracts. As the median tract may be a bit longer or shorter in different subjects, the endpoints don't always have corresponding points in all subjects ________________________________ From: freesurfer-bounces@nmr.mgh.harvard.edu freesurfer-bounces@nmr.mgh.harvard.edu on behalf of Hua, Jessica jphc55@mail.missouri.edu Sent: Thursday, April 23, 2020 4:01 PM To: freesurfer@nmr.mgh.harvard.edu freesurfer@nmr.mgh.harvard.edu Subject: [Freesurfer] Trac-All NaN
