[Insight-users] wrap_itk, python, and dicom

[Mario Ceresa]

Hello David!
I use 3.16 as well. I think the difference might be the version of
wrapitk. The one that comes with itk is outdated. The newest one can
be found at:

http://code.google.com/p/wrapitk/

Please let me know if that solves your problem,

Mario
