# Starting a Growth

> Begin a new monitoring session by streaming live growth data

To monitor a growth in real time, you start a stream from the Monitor page. Click **Monitor new growth** (or press <kbd>Ctrl</kbd>+<kbd>N</kbd>), then pick how you want to send data to Atomscale.

## Entry Points

<CardGroup cols={2}>
  <Card title="Screen capture" icon="video">
    Stream growth data by capturing a screen or window from your browser. Best when your RHEED
    software runs on the same machine as your browser.
  </Card>

  <Card title="Programmatic" icon="code">
    Stream growth data programmatically via the Atomscale Python SDK. Best for headless systems or
    custom acquisition pipelines.
  </Card>
</CardGroup>

### Screen capture

Choose the window or screen showing your instrument output and frame the capture area. Frames are uploaded and analyzed continuously while the session runs.

See [Screen Capture](/platform/reference/connecting-data/screen-capture) for the full capture flow, including positioning the capture area and configuring stream settings.

### Programmatic

Use the Atomscale Python SDK to open a session and stream RHEED frames from your own systems.

See [Programmatic](/platform/reference/connecting-data/programmatic) for connecting via the SDK, and [Stream RHEED](/sdk/stream-rheed) for the streaming API.

<Note>
  Once the stream starts, you're taken to the live [Session View](/platform/reference/monitoring/session-view),
  where the growth appears in the Ongoing group as it runs.
