[Insight-users] Read DICOM series with Python wrap

[Paul Novotny]

In my experience you can't get the SeriesUIDS with Python. I think that
function returns a string representation of pointer? Anyway, the way I
have been able to read DICOM series in Python is with the following:

        name_generator = itk.GDCMSeriesFileNames.New()
        name_generator.SetDirectory(directory)
        filenames = name_generator.GetInputFileNames()
        reader.SetFileNames(filenames)

The key is the GetInputFileNames instead of using GetFileNames. I am not
sure if this reads all files in the directory, or the first Series. For
me, these have been the same thing. So you might have to play with it to
get a specific SeriesUUID.
