Step3, 5-8 all produce some problem. The file Pic3D.nrrd can not be opened.
The Ouput creates the message from fprintf shown below, so dataNodes is empty.
mitk::StandaloneDataStorage::SetOfObjects* dataNodes = mitk::IOUtil::Load(argv[i],*ds);
if(dataNodes->empty()) { fprintf( stderr, "Could not open file %s \n\n", argv[i] ); exit(2); }
