[vtkusers] Simple vtkStructured grid file wt. scalars.

[Fletcher, Bob (GEAE)]

I have to be doing something stupid.  I'm trying to write  a simple vtk
structured grid data file.

Here is a vtk data file, extracted from office.vtk   Does anyone else's set of
eyes see the problem?

When I try to read it  on a recent nightly build on HPUX 10.20 I get the error
below.
The script below shows the geometry, but I'm not getting the scalars.

c0529$ vtk short.tcl
ERROR: In vtkStructuredGridReader.cxx, line 390
vtkStructuredGridReader (0x403209b8): Unrecognized keyword: scalars


---------------------------------------------------
Here is a script to read it.  The same script will read and display kitchen.vtk
without errors, but I can't see any difference between the Office.vtk file, and
my short file.....
