Colored Surface-- Display a surface view with colored voxels PURPOSE: Display a shaded surface from a volume and color the voxels which appear on the surface according to colors specified in a second color volume. USAGE: Similar to the surface operation, except that the user is prompted for both the SPIDER volume to be surfaced and a second SPIDER volume which contains a color assignment for each voxel. Both volumes must have the same dimensions. Colors should be 0 --> 7. The more colors requested, the less the intensity range available within each color. For three colors about 58 intensities are available. Currently the opteration will load a default color assignment as follows: 0 = blue, 1 = green, 2 = red, 3 = yellow, 4 = cyan, 5 = magenta, 6 = white. NOTE: The operation can also accept a arbitrarily ranged color volume and will automatically partition the color range into the number of colors requested in the surface munu. However I do not recommend this method of use, as it may disappear in the future. NOTE: This operation is a bit buggy and may not work properly twice in the same Web session. If you have problems please restart Web.
