[Insight-users] Cannot change the series description (0008|103E) of a dicom file using ITK

[Mathieu Malaterre]

Hi Luis,


  No need for a DICOM guru here. "0008|103e" simply means the pair of
unsigned short 0x0008,0x103e. AFAIK the c library sscanf/printf should
support both hexadecimal representation. I do not know whether we
(ITK, GDCM?) are restricting it, or if this is an issue with the C
library.

  Anyway Andreas this should not be hard to track down. Please let us
know if this is an issue in ITK and/or GDCM.

Thanks,
-Mathieu
