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

In general, it mostly looks ok. 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.

Hi Corinna
how does the rest of the aseg.mgz look? Is it accurate? Bruce

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?
