Sequence missing from a scan

Hi Tuomas,
Do you know if the data makes it to the server at all? All incoming DICOM data gets logged in the received.log file. Entries there look something like this:
2021-10-14 11:04:00,153 - admin:/data/xnat/prearchive/Test_01/20211014_110350413/Test_01_01_MR_02/SCANS/7/DICOM/1.2.276.0.7230010.3.1.2.0.31909.1624637609.925-7-46-2z8kcp.dcm
That’s for a file uploaded using the XNAT desktop client. It’s a little different for data sent via C-STORE:
2021-10-14 11:07:08,931 - TERM@/10.1.1.1:58687:/data/xnat/prearchive/Test_01/20211014_110650893/Test_01_01_MR_03/SCANS/5/DICOM/1.2.276.0.7230010.3.1.2.0.31909.1624637609.925-5-60-2ynj6a.dcm
The only difference is that data uploaded through the REST API (e.g. with the desktop client) has the name of the user who uploaded the data, while data via C-STORE has the title, IP address, and port of the AE that sent the data (the port is kind of useless because it’s an ephemeral port on the client side).
The main point is that you can tell which scans were received based on the path:
/data/xnat/prearchive/Test_01/20211014_110650893/Test_01_01_MR_03/SCANS/5/DICOM/1.2.276.0.7230010.3.1.2.0.31909.1624637609.925-5-60-2ynj6a.dcm
The highlighted parts of that path are:
- The root prearchive folder
- The project where the data is to be archived
- The label for the new session
- The scan (i.e. series) number
- The study instance UID
Between those bits of info, you should be able to verify whether the data arrived in the first place.
If the data did arrive, check to see if it happens to be lying around somewhere, maybe in the prearchive or cache folders. Something like:
find /data/xnat/prearchive -name 1.2.276.0.7230010.3.1.2.0.31909.1624637609.925-5-60-2ynj6a.dcm
You can also check if there are any entries in other log files around the time that the data arrived that might indicate what happened during the archive operation.
