[Insight-users] GDCM Series Dicom reader for some Siemens MRI Dicom data

[Mathieu Malaterre]

Andrew,

	Thanks a lot for tracking this issue down. Do you have permission to 
share this image. I would like to add it to the gdcmData baseline to 
make sure that each night we are able to read both SIEMENS DICOM file: 
the buggy one (with wrong length) AND the correct one (the one you have).

Thanks for your help,
Mathieu
