[Insight-users] Analyze Image Reader Error

[Luis Ibanez]

Hi Raluca,

The Analyze reader is not being registered by
default in the ImageIOFactory at this point.

This means that you have to explicitly create
the AnalyzeImageIO object and connect it to the
ImageFileReader.

The runtime error you get is probably due to the
IO factory trying to find an ImageIO capable of
reading your image file and... failing to find one.
Normally this should result in an exception being
thrown.

Please try code like the following:


typedef itk::AnalyzeImageIO   ImageIOType;
ImageIOType::Pointer  imageIO = ImageIOType::New();

typedef itk::ImageFileReader< ImageType > ReaderType;
ReaderType::Pointer reader = ReaderType::New();

reader->SetImageIO( imageIO );
reader->SetFileName( filename );

try
   {
   reader ->Update();
   }
catch( itk::ExceptionObject & excp )
   {
   std::cerr << "Exception caught !" << std::endl;
   std::cerr << excp << std::endl;
   }



Let us know if you find any problems


   Thanks


      Luis
