I am writing to ask about an error in pre-processing in TRACULA.

After making FSL radiological header of dwi_orig_flip.nii.gz, an error occurs.

When the name of file is changed from dwi_orig_flip.mghdti.bvals to bvals, I can't find the file dwi_orig_flip.mghdti.bvecs.

So an error is mv: rename /volumes/mybook/Anri/diffusion_tutorial/HC_025/dmri/dwi_orig_flip.mghdti.bvals to /volumes/mybook/Anri/diffusion_tutorial/HC_025/dmri/bvals: No such file or directory caused.

The content of bvals is not overwritten.

I attached my configuration file, the error log and bvals.

-error log-

Many thanks for your help.
