Hi Corinna

if you upload the dataset I'll take a look.

Hi Bruce, I was just wondering if you had any suggestions on how to fix the corpus callosum labels?

There are regions which are labelled as hypointensities, but should be CSF or gray matter, particularly around the parieto-occipital fissure (see attached). Much of the fornix and corpus callosum is also just labelled as  left/right cerebral white matter.

        Hello all,
        I am examining diffusion tracking in the corpus callosum of individuals with
        periventricular leukomalacia (PVL). The corpus callosum is particularly
        small and the anterior and mid-anterior labels are being applied to the
        fornix (see attached Fornix_labelled_as_CC.png). The midposterior and
        posterior look ok, while the central is very small, maybe one voxel in size.

        The wm segmentation, seen with ?l.white, also shows segmentation defaults
        with the anterior corpus callosum (see attached images). I tried to correct
        this using control points, which you can see did not fix the segmentation.

        Any suggestions?
