Hi, I'm wandering if its possible to convert a label into a volume so that it fills the space between the white and pial surfaces used in calculating thickness. That is, if the label is drawn on the wm surface, is is possible to determine what points on the pial surface are used to calculate the thickness of that label? I've been playing with the --proj option in mr_label2vol. The --help states that --proj frac "means that start, stop, and delta are relative to the thickness at each vertex." I tried using the start, stop and delta values provided in the example (0, 1 .1), but it doesn't seem to completely fill the area between the two surfaces. I've also tried plugging in other values and can't seem to get it right.Is there soemthing I'm missing? Thanks, Alex
