[Insight-developers] GDCM IO and metadata copying

[Miller, James V (Research)]

Just so people know, one use of sequences in DICOM is for specifying
contours and landmarks. This is a way to report segmentation results
and a way for specifying "ground truth".

Hi,

when GDCM IO is copying metadata from image, it does not distinguish
between simple tags and sequence of tags. As a consequence, it segfaults
when reading DICOM file with sequence tag. You can grab such a file from
http://www.vision.ee.ethz.ch/~pcech/bugreports/ITK-20041108/

Attached patch contains a workaround. It will skip all tag sequences.  
I suspect that the proper fix would require more than just copy all tags
from sequence, so I better leave it to someone with better knowledge of
DICOM format.

Regards,

Peter Cech
