[vtkusers] Problems with vtkDataReader.cxx

[Sérgio Augusto]

Hi everyone,

I'm trying to execute some example files to learn about vtk but when I try
to execute one of these examples I get this error:

ERROR: In C:\Dashboards\Releases\rc-VTK-5-4-2\VTK\IO\vtkDataReader.cxx, line
> 462
> vtkStructuredGridReader (0B3A0940): Unable to open file: Data/subset.vtk
>

The code of the example is this:

package require vtk
> package require vtkinteraction
>
> vtkLookupTable lut
> #    lut SetNumberOfColors 8
>     lut SetNumberOfColors 16
> #    lut SetNumberOfColors 32
> #    lut SetNumberOfColors 64
> #    lut SetNumberOfColors 128
> #    lut SetNumberOfColors 256
>     lut SetHueRange 0.0 0.667
>     lut Build

> vtkStructuredGridReader reader
>     reader SetFileName "Data/subset.vtk"

> renWin SetSize 500 500
>
> iren AddObserver UserEvent {wm deiconify .vtkInteract}
> renWin Render
>
> wm withdraw .

Does anyone knows what is it?
I'm using vtk 5.4.2 downloaded from
http://www.vtk.org/VTK/resources/software.html and the examples are from
http://scv.bu.edu/documentation/tutorials/VTK/#INTRO

Thanks,

Sergio
