[vtkusers] help please about vtkVolume16Reader

Hi

You should pass a prefix of the files that compose a volume
to the SetFilePrefix() method, not a filename.

If you have let's say, five slices, they may look like:

quarter.1
quarter.2
quarter.3
quarter.4
quarter.5

and you pass:

SetFilePrefix( "C:\Data\quarter" )

assuming that files are in the Data directory on drive C:\

For details look at medical3.cxx example in VTK examples

Of course you can name your prefix as you like, but the ".1", ".2",...
extensions are important.
