Hi, I'm having issues with tkmedit. I'm doing visual inspection and I checked tkregister to be sure that the white matter is outlined in the functional image. However, when I open tkmedit for surface and cortical segmentation, it doesn't show up the red and green lines that distinguish the boundaries of the grey and white matter. It had previously and I put a few control points but now it doesn't show up at all. Why might this be and how can it be fixed? Thanks! Talia
