Hi,
I’m working on sending and encapsulatedPDF through a python script to the Orthanc Server. On the first try I obtained this log:
Store SCP Failed: DIMSE: Odd Fragment Length: 1275
Then, as suggested in this thread I ran the storescp utility and obtained this output:

I: Association Release
So the transmission worked and the association is not aborted or timed out as in the Orthanc case. However, the utility highlighted that the value length of element (0042, 0011) (The document encapsulated) is odd, while every DICOM element must have an even value length. Then I investigated further and found that the DICOM standard implements this element where you can specify the Value Length of (0042, 0011), even if it’s odd. However, even after adding this element, I obtained the same result from Orthanc:
Store SCP Failed: DIMSE: Odd Fragment Length: 1287
While the storescp utility worked as before with the warning on (0042, 0011). In the end, I managed this padding the pdf to an even value length, appending a ‘\0’ at the end of the file, but is this the right behavior from Orthanc? Thank you.
