[vtkusers] SLC Reader eror

Maybe you have the environment variable VTK_DATA set to "../../../vtkdata" 
on your machine.  If that's the case, then the vtkSLCReader is trying to 
open your vtkdata directory as a file.  Try changing your script as follows:

if { [catch {set VTK_DATA $env(VTK_DATA)}] != 0} \
         { set VTK_DATA"../../../vtkdata" }
   reader SetFileName "$VTK_DATA/mridata/breast3.slc"

I hope this helps.
