Problems using the compressed uploader

[André H.]

Hello everyone,

I have problems uploading data to XNAT (1.8.4.1) using the compressed uploader. I tested it with data from the internet, and it worked, but with our medical data it does not. SOP Instance UID, Study Instance UID and Series Instance UID are all there. The only main difference seems to be Transfer Syntax UID, which is set to "Explicit VR Little Endian". I get the message "Found 0 DICOM files", a screenshot is attached.

Can anyone help me?

Kind Regards

André

I doubt that it’s the transfer syntax, since that’s the default transfer syntax for XNAT’s DICOM importer. From org.nrg.xnat.archive.GradualDicomImporter:

 

private static final String  DEFAULT_TRANSFER_SYNTAX = TransferSyntax.ExplicitVRLittleEndian.uid();

 

Are there any messages in the log files on the backend? Do you end up with anything in the prearchive (I’m guessing no, but it’s worth checking).

I just double-checked the logs, they don't seem to mention anything. The prearchive is also empty. Are there maybe other fields that are required for the upload to work? The data is anonymized by a python script that is pretty strict with what it throws out.

[Herrick, Rick]

There’s nothing that would cause this that I can see with a quick glance through the code. Could you share a sample of the data that you’re trying to upload? I’m presuming you run the Python script on the data first locally then upload the data. I’d be interested in the data that’s been processed by the Python script if that’s possible.
