Review before you upload
When you add a recognized file in the upload panel, DataErai shows a metadata preview before the upload starts:- See the extracted fields, grouped to match the instrument (for example, XRD shows X-ray source, Geometry, and Scan).
- Edit any value inline, or switch to the raw JSON view.
- Use the Attach toggle to decide whether the extracted metadata is saved with the asset.
xrd or tem-session) to help with organization and search.
Very large files (over about 100 MB) skip the in-dialog preview, but their metadata is still extracted automatically after the upload finishes.
Re-run extraction later
If a file uploaded before extraction was available, or you want to refresh it, open the asset and choose Extract metadata to run it again.Validation hints
For some formats, the preview flags likely problems so you can catch a bad file early — for example, an XRD scan with an unusually low tube voltage, zero current, or a missing anode material.It’s searchable
Extracted metadata is available to search alongside the metadata you add yourself, so you can filter assets by instrument settings and other captured fields.Next steps
