[ITK] [ITK-users] itk - Writing dicom files from single 3D file

[AI]

Hello,

I would like to write Dicom files from a nifti image files using
DCMTKImageIO. In the code below, I read a nifti file using
itkImageFileReader, and then try to write dicom files using
itkImageSeriesWriter. I was not able to do it, probably because of the
SetMetaDataDictionaryArray method, that I don’t know how to use since I
don’t read dicom series as input. Can you help me with that ?

Thank you very much,

Audrey
