[otb-users] GDALImageIO error

[Poughon Victor]

Hi

I am writing an OTB application and getting the following error at runtime:

    itk::ERROR: GDALImageIO(0xc35a30): Dimensions are not defined.

Any ideas what it means?
Here is the DoExecute of my (very simple) application. i think the problem 
comes from the way I am using itk::NaryAddImageFilter, but I don't know:

    FloatVectorImageListType::Pointer inList = GetParameterImageList("il");

    std::vector<ExtractChannelType::Pointer> 
extractChannelFilters(inList->Size(), NULL);
    NaryAddImageFilterType::Pointer naryAdder = NaryAddImageFilterType::New();

    // For each input image
    for (unsigned int i = 0; i < inList->Size(); i++)
    {
      // Extract first band
      extractChannelFilters[i] = ExtractChannelType::New();
      extractChannelFilters[i]->SetInput(inList->GetNthElement(i));
      extractChannelFilters[i]->SetChannel(1);

      // Add it
      naryAdder->SetInput(i, extractChannelFilters[i]->GetOutput());
    }

    // Divide by N
    MultiplyImageFilterType::Pointer divideFilter = 
MultiplyImageFilterType::New();
    divideFilter->SetInput(naryAdder->GetOutput());
    divideFilter->SetConstant(1.0f/inList->Size());

    // Write
    SetParameterOutputImage("out", divideFilter->GetOutput());


Thanks
