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
