Note that tracula doesn't extract from the atlas the exact spatial location of the tracts. It only extracts which anatomical labels are the neighbors of the tract at each point along its trajectory. So it's not as sensitive to misregistration as a voxel-based analysis would be. Our paper disc

Hi Gabor - If you provide the DWI dicoms directly, tracula uses mri_convert to convert them to nifti, and mri_convert doesn't read directions from the header, it looks them up from: $FREESURFER_HOME/diffusion/mgh-dti-seqpack/ This should be fine assuming you use the same standard Siem
