[Insight-users] RE: GDCM image size reading

Mathieu:
I have just built the DicomImageReadPrintTags example and run it
against the dicom image file. Unfortunately, the program crashed,
complaining the memory could not be "read". In the command line,
it shows "Meta Group Length 166", which belongs to (0002,0000).
There is no indication where it stopped on the command line.
Anyway, I have attached my own tag printout as an alternative.
It virtually contains everything needed for interpret the image
data. For the sake of the confidentiality of patient information,
I have wiped out the patient personal information. Everything
else are intact.

George,
Before you send us any images could you simply run:
$ ./bin/DicomImageReadPrintTags image.dcm
And then send us the output of the program.
Thanks
