Hi Benjamin - This means that the initial guess for the path based on the
atlas average is way off, due to poor alignment between your subject and
the atlas subejcts. Ways to get around this is to look into the options
for registration, whether diffusion-to-anatomical or anatomical-to-atlas,
and to increase the number of control points used for fminor.
Hope this helps,
a.y

Dear Freesurfer experts,
we have a problem with the forceps.
After the first trac-all we had a forcpes minor with a really unusually
structure so we tried to fix it with an rerun of the trac-all.
The result was a forceps minor with a third thigh in the sagittal axis.
We did a second rerun and now the forceps minor normalized.
Our problem is that we don´t know if we should do more trac-all reruns by other
patients with difficult tracula or how we should interpret this result.
Do you have any ideas to solve this?
The second problem is that we have many many tracula results with incomplete
forcepes minor or major.
We know that the forcepes are the most difficult tracts because of the
curvature but do you have some ideas to fix that problem?
Kind regards
Benjamin
