Hi,

That's my fault- I changed the original yesterday. I've changed it back
now...

The original is particular to Vidya's data and is here:
http://www.bioengineering-research.com/vtk/segmented.tcl

And a new one, that is more general here:
http://www.bioengineering-research.com/vtk/segmented2.tcl

Bill Lorensen's original scripts are here:
