Dear all, I am very new to using TRACULA and Freesurfer. I am trying to apply tracula on the provided tutorial data. When I ran the command trac-all -prep -c dmrirc.tutorial, after eddy current correction, I get this error:

I only defined the data path, output path, subject list and dcmlist. The problem seems to be related to bvecs file, I looked at it, and it seems to have 0.0000 in the beginning. Could this create a problem? Thank you. Best, -- D.
