Hi, I'm currently testing out the surface extraction using the Colin dataset.
Everything comes out satisfactory - except, the segmentation generated tends to leave out a large chunk towards the anterior end of the brain. http://www.cs.umn.edu/~tjarvis/colin1.gif http://www.cs.umn.edu/~tjarvis/colin2.gif I'm using a talirach coordinate space volume, so cropping the hemisphere, and seting the AC is fairly straight forward. I have error correction on, 'extract cerebellum and segment' on, and 'do not identify sulci'. also the volume orientation is correct, peaks are set correctly, and any other option I see Any idea what I could be missing here? (I don't think it's the dataset) Thanks! --------------------------------------- Timothy R.
