Hi Linnea,
I don't see any issue in the screenshots you sent. I couldn't find
freeview_T207_dtifit_FA.nii.gz.png in the attachment, either. Also your
second screenshot is comparing FA image with a b0 image, which will look
somewhat inversed.
Best,
Ruopeng

Hi,
We have run TRACULA on a couple hundred subjects and the quality
control shows that most of them are OK, but in a few subjects the
dtifit_FA.nii.gz images look strange in FreeView. The image
intensities appear reversed in FreeView (see
freeview_T207_dtifit_FA.nii.gz.png) but look normal in Fslview (see
Fslview_T207_dtifit_FA.nii.gz.png). T205 is an example of a subject
that looks normal also in FreeView (see
fslview-freeview_T205_dtifit_FA.nii.gz.png), as most of our
subjects' dtifit_FA images do.
207's dwi_orig image looks fine in FreeView (see
freeview_T207_dwi_orig.nii.gz.png) as do all its L1,L2,L3,V1,V2,V3
etc. images.
I'm puzzled as to what has happened here. Since the image looks fine
in Fslview I'm inclined to think this is a FreeView issue?
Thank you,
Linnea Marie
