Hi there,
I finally came to a point, that I am able to write dicom-Files with
IDL. I create new objects with the following code:
obj = OBJ_New('IDLffDICOMex', filename,
SOP_Class='ENHANCED_MR_IMAGE', /NON_CONFORMING, /CREATE)
I'm calculating parameter-maps and write them into the files. This
works so far: I calculate the maps and write six different files.
Since I'm evaluating three slices of the heart I do this iteratively.
When IDL comes to the point where it wants to write the six maps for
the second slice into the same directory but with different filenames
I get an error right after calling the obj = OBJ_New line:
OBJ_NEW: Error: Unable to add media storage SOP instance UID ,
Invalid characters in value for this VR
The problem is, that this tag (0002:0003) is "set to a new ITT Visual
Information Solutions-generated value" and I don't know how to solve
this problem.
Maybe someone is able to give me a hint..
Andreas

Getting more and more strange. Evaluated six datasets yesterday. But
now I have the old problem. For the moment it looks random to me. And
this discussion is becoming kind of a soliloquy;)

Looks strange for me. I formerly put the dicom-writing in a program
that was called with the data-matrix and a filename. I checked the
data-type and some other stuff and then called all the stuff to
finally write the dicom-file.
I changed my program into a function that is called with the two
parameters data and filename and returns just an integer 0. And now it
looks like it works. For me, it becomes not clear why it works now,
but it works.
