Fixing stuck uploads

If data you uploaded has not appeared in your XNAT project, it is probably waiting in the prearchive — a holding area that uploads pass through before they are archived into a project.

Data usually stops there when:

• a DICOM dataset matching an existing session is sent again
• part of a session is uploaded separately

Finding your data

Go to Upload on the top menu, then Go to prearchive.

Select the session and choose Details to review it. Below is an example of a session in conflict.

From here you can download the session or individual scans to check the contents before deciding what to do with it.

Archiving the data

This choice matters, and it cannot be undone easily:

• Archive merges the data into the existing session in your project. Use this when the upload is the missing part of a session that is already there.
• Modify and Archive lets you change the details first. Use this when the data should become a separate session, or when the session or subject labels are wrong.

Caution

If you are not sure whether the data belongs to the existing session, download it and check before archiving. Merging the wrong data into a session is harder to unpick than archiving it separately.
