[Insight-users] Problem Reading DICOM Image Series

[Antonio Gómez Barquero]

Sorry for not answering, but I was forced to finish some work with a near deadline!

Now, I know where is the error, is in the last line of these:

	std::string seriesIdentifier;
	seriesIdentifier = seriesUID.begin()->c_str();
	FileNamesContainer fileNames;

	fileNames = nameGenerator->GetFileNames( seriesIdentifier ); <--- HERE IS THE ERROR

It goes with the iterator through all the dicom image series I have in the folder, but when it reaches the filename, it write in this variable, the direction of the 92º image! Why can be that?

Because of that, only one 2D image is read, not the whole 3D volume.

Thanks again!

Antonio

Your code looks fine ( and sounds like it is running fine) to me. SeriesEnd should be an invalid value - it is used it indicate that you have iterated over the entire string. Does your program run ok? What do you expect seriesEnd to contain?
