How do I use the Discovery RA app and the data parser?

  • Updated
Discovery RA is Sibel’s research app for streaming and downloading raw sensor data. It does not use Discovery Hub. Sibel provides a parser that converts the raw .shrd files into readable .csv files.

Discovery RA vs. Discovery

Both apps use the same sensors, with a different data collection mode. Discovery RA supports automatic and manual recording; Discovery uses automatic only. A sensor can be paired with only one app at a time. To move a sensor from Discovery RA to Discovery, change its session mode to automatic and then Unpair it in Discovery RA.

Get started

  1. If Sibel did not supply an iPad, download Discovery RA from the Apple App Store.
  2. Open the app and select Sign Up. Enter a username, email address and password. You need an internet connection. If sign-up fails with your institutional email, contact us.
  3. Enter a Session ID and select Start Session. Data is labeled with this Session ID.
  4. Select + Add Sensors, find the sensor by its serial number and select Pair if asked. Keep sensors within 2 meters of the iPad. You can pair up to 8 sensors at once.

If you miss the iPad’s Bluetooth pairing prompt, go to iPad Settings > Bluetooth, forget the sensor, and pair it again.

Getting the data off the iPad

If your study uploads to the cloud: in Discovery RA, go to Settings > Cloud and check that Data Upload and Debug Log Upload are on, as your study setup instructions say. Keep the iPad unlocked, on Wi-Fi and with the app open until Pending Upload reaches zero. If uploads stop, select Reset Upload Cache. This does not delete data.

If your study keeps files locally: open the iPad’s Files app > On My iPad > Discovery RA. The shrd folder holds the raw data, event holds any events you added, and log holds app logs. You can ignore Storage. Move files with AirDrop or a computer.

When you contact us about a problem, the files in the log folder help us most. They record app actions, not subject data.

The parser

  • Sibel sends the parser as a .zip for Windows, macOS or Linux. Tell us which system you use.
  • It runs from the command prompt or terminal. The package includes instructions.
  • If the parser is blocked on a managed computer, contact your IT department and us.
  • Large files can take several minutes. Wait for processing to finish before opening the output folder.
