[Insight-users] wrap_itk, python, and dicom

[David Fuentes]

Cool. thank you very much Mario!

What version of ITK are you using ?


my GetKeys() is just returning a string


print metad.GetKeys()
'_30a1941b00000000_p_std__vectorTstd__basic_stringTchar_std__char_traitsTchar_t_std__allocatorTchar_t_t_std__allocatorTstd__basic_stringTchar_std__char_traitsTchar_t_std__allocatorTchar_t_t_t_t'



I am using ITK 3.16.



thanks again,
df
