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:

My config file is as simple as possible. 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,
