Data Items

Data items represent instrument recordings or measurements: a RHEED stream or video, an XPS spectrum, an SEM micrograph, a tool state log, and so on. They can arrive through an upload, a managed integration, or a streaming interface; a data item is not always a single uploaded file.

​

Data Types

Every data item is classified by its data type. The platform supports these types, grouped by category:

​

RHEED

​

Spectroscopy

​

Imaging

​

X-ray

​

Other

​

Pipeline Status

After upload, each data item moves through a processing pipeline. The status reflects where it is in that process:

​

Associations

Each data item can be linked to: You can set these associations from the Data catalog table or from a data item’s detail page.

​

Adding Data

Choose a method based on how the source is available:

• Manual upload: use Add Data > Upload for files you already have.
• Managed integrations: use the desktop app to collect camera data, tool logs, and files from local sources. See Integrations.
• Screen capture: use Add Data > Stream to stream a RHEED display. See Screen Capture.
• Programmatic ingestion: use the Python SDK for custom upload or streaming pipelines.

In the browser, Add Data > File Watcher offers the legacy standalone application. New setups should use managed integrations. The desktop app does not show that legacy tab. See Connect for prerequisites and authentication.

​

Find and Analyze an Item

In Data Catalog, items without a physical sample are hidden by default. Turn on Show … items without a physical sample in the footer to include them. See Finding Collected Data if an integration’s data is not where you expect. Check the processing status before expecting derived results. Use an analysis notebook to investigate accessible raw data and results; tell the assistant which item or growth you mean.
