Hi all, I'm trying to display statistical values in color on a surface. The stat values are in voxels, originally, but are translated from a NIFTI format file to a .vtk format. I've got a binary version of the object (1's where the object is, 0's everywhere else). Through comments on this list, I've figured out that if I use the calculator to create a copy of the binary scalar values (and rename them as something else, e.g., "surface"), and then use Append Attributes to combine the stat data scalars with the surface scalars (from the binary image), I can then use Contour to make the surface (using the "surface" scalars) and then color this surface with the stat data scalars. So far so good.
Here is my problem: When I do Append Attributes, the stat data scalars all get changed to a range of 0 to 1, even though the stat data file that was used in Append Attributes claims to have values of: [0, 128.619]. So, what is going on? Why is Append Attributes not appending attributes without changing their values?? Any ideas? -Tom _________________________________________________ P.
