Hi Kiely,

Have you checked your inter and intra subject registrations? The control
points going off the dwi is not only for one paths but for all the paths.
If the registration goes terribly wrong, this can happen. You can take a
look at

/dmri/lowb_brain_anat.flt.nii.gz (For intra subject registration diff-anat)

and

/dmri/brain_anat_mni.nii.gz (For inter-subject registration anat-mni)

I would start by checking that first.
