[Insight-developers] GDCM Failure

[Miller, James V (Research)]

Hans, 

Below is a diff between the DICOM tags in two of the files. The files have different
Study UIDs.  When I load this directory into DICOMWorks, each image is shown as belonging
to its own study.  What would you like GDCM to do with data? Are you expecting a 3D
volume, a 4D volume?

Subject: [Insight-developers] GDCM Failure


Matheiu (and others),

Our group is attempting to use the ITK/GDCM components to convert dicom 
images to the newly added nifti format using the cast convert program.  
For the most part, this works very well, but there is a failure in 
making the dicom file list from a directory for some types of data.


I have an example data set that causes GDCM to fail:
http://www.psychiatry.uiowa.edu/users/hjohnson/castconvert_failed.tar.gz


This same data set can be converted to nifti file format with the afni 
to3d tool, and with the BRAINS file readers/writers.

Any help or advice would be greatly appreciated.

Hans
