[ITK-users] Question about ImageFileReader

[Tim Allman]

Perhaps I misunderstand the documentation but I have written the 
following code with the idea that I could read arbitrary image file 
types and let the ImageFileReader instance figure out which ImageIO was 
needed. The files are Nrrd which seems to be supported but the last line 
fails with the error below.

Any suggestions?

      std::string name = 
/Users/tim/devel/ConvertToDicom/Case005/out_000.nrrd

     typedef unsigned short PixelType;
     typedef itk::Image<PixelType, 2u> Image2DType;
     typedef itk::ImageFileReader<Image2DType> ReaderType;

     ReaderType::Pointer reader = ReaderType::New();
     reader->SetFileName(name);
     reader->Update();

itk::ImageFileReaderException: 
/Users/tim/usr/local/ITK/Universal/Debug/include/ITK-4.5/itkImageFileReader.hxx:143:
  Could not create IO object for file 
/Users/tim/devel/ConvertToDicom/Case005/out_000.nrrd
   Tried to create one of the following:
   You probably failed to set a file suffix, or
     set the suffix to an unsupported type.

Thanks,
Tim
