[Insight-users] the problem in Vtk2Itk.

[yasser salman]

Hi Luis.., 
 i added these lines below after vtk2itk connection
and disconnect the itk filters the same error message 
appeard again .., when i disable these lines 
the message disappeard , So i think Volume didn't 
convert correctly  to ITK...,

typedef itk::ImageFileWriter< InternalImageType>
WriterType;
  WriterType::Pointer writer = WriterType::New();
  writer->SetFileName("C:/Image.vtk");
  writer->SetInput( cast->GetOutput() );
    writer->Update();
 plz informe me what can i do to cross over this
problem,..thanks ,,
