Hi Andi - I managed to track this down by looking at the complete data set
that you sent me. Your bvals file has no b=0, there's only b=2075 with
some b=5 interspersed. The b=5 volumes must be your baseline volumes but
unfortunately there's no way for the program to know this right now.

Dear Tracula team,
I have noticed in a multisubject tracula analysis, that the posterior density
in many if not all paths in the path.pd.nii.gz file is just a bright
one-dimensional curve, rather than a true distribution.
The path.map.nii.gz is empty. This is true for both flirt and bbreg
Hi Andi - The most common problem that would cause all or almost all
pathways to fail is an incorrect gradient table. You can do a sanity check
on that by looking at the primary eigenvectors from your tensor fit
(dmri/dtifit_V1.nii.gz). See also my answer to Fernando earlier today.
Hope
