In the attachment are 2 dicom dose files. The function DICOM_FindTag can find $7FE0,$0010 in one of the files but not the other. (I am sure the tag is present in both files.) Would anyone know what the problem is and how I would be able to read the data from both files? I have noticed that the file that does not work has a transfer syntax of explicit VR little endian but I don't know if that is relevant.
