[IGSTK-Users] Matlab DICOM compatibility

[Patrick Cheng]

Hi Ryan,

The IGSTKImageReader is doing some safety checks internally. For 
instance, if you are using CTImageReader, then it will check the 
modality tag in the DICOM image header to see if this is a CT image. 
Most likely, in your case, the DICOMWrite in Matlab altered the original 
tags which cause the IGSTKImageReader to fail.

Thank you,

Patrick
