[ITK-users] Can't iterate over MetadataDictionary from GDCMImageIO

[Matt McCormick]

Hi Marcos,

If BUILD_EXAMPLES and BUILD_TESTING is turned on in your ITK CMake
configuration, and the ITKData target has been built, the example and
testing data are available in the build tree. Run

  ./bin/DicomSeriesReadPrintTag ./ExternalData/Testing/Data/Input/DicomSeries

and the tags will be printed out.

Hope this helps,
Matt
