Hi Marena - How does the T1 of this subject and its freesurfer segmentation
(aparc+aseg) look? In the image the brain looks truncated, is that the case
with the T1?
Anastasia.

Subject: [Freesurfer] Tracula registration failure
External Email - Use Caution
To the Tracula team:
I am attempting to complete my first project using the Tracula pipeline on a
mixed dataset of autism, schizophrenia, and control adult brains. I ran the
tracula prep, bedp and path steps for the autistic subject in question without
receiving any error messages. However, when I attempt to view the registration
of the FA.bbr.nii.gz image to the MNI brain the registered image appears as a
completely white, roughly brain-shaped mask. This has not occurred with other
subjects from the dataset. I have attached a screenshot from freeview for
reference.
When I load the subject's dtifit_FA.nii.gz in freeview it appears to be
relatively normal. Is this a fatal error in the registration process, and is
there any way to correct it?
I have also attached the log file for the subject in case this is helpful.
Thank you for your help,
Marena
