Hi, 

I processed some subjects in TRACULA for a longitudinal evaluation.

I registered all of them in the MNI template (set doregmni = 1 

set mnitemp = $FSLDIR/data/standard/MNI152_T1_1mm_brain.nii.gz).

I checked the registration of my dtifit_FA.bbr.nii.gz with the MNI of all subjects.

However, when I performed the group analysis, I got more NaN than expected and I checked the images and the results are outside the MNI template (I am sending a picture).

I went back and checked the registration of the paths. Despite the dtifit_FA.bbr.nii.gz is correctly registered in the MNI, the paths aren't.

I am struggling here to find solutions. I really appreciate any insight to help me to solve this issue.

Thanks in advance, 

Gabriela Longo
