I am using slicer to display an image using the 'render1' lut. How is the color of an edge (from the 2nd input volume) determined? Can I set this color (perhaps by modifying the 'render1.lut' file)? When I use the default greyscale lut, the edge is red. When I use the render1 lut, I do not see the edge. The command I am using is: slicer cope1 hippocampus_left -s 2 -l render1 -L -i -0.646911 4.038347 -x -50 /tmp/sliceX_050.png where volume 'hippocampus_left' is a binary 0/1 volume Thanks, - BettyAnn
