Follow these steps to extract all archived data from an mCerebrum instance.

  1. Stop the study if it is currently running.
  2. Launch the DataKit application and ensure the timer is not running and its state is inactive
    • If the timer is still active, reboot the phone to force the connection between mCerebrum application to reset.
  3. Plug the phone into a computer
  • Apple
  • Windows
    • Plug the phone into the computer and wait for Windows to finish installing drivers
  1. Locate and copy the following folders to your computer
  • Internal Memory: /Android/data/org.md2k.datakit/files
  • External Memory if equipped: /Android/data/org.md2k.datakit/files

These field deployments typically range from 14-30 days and result in a minimum of 423 million data points up to a maximum 907 million points per individual.

The paper only breaks down the aggregate sampling rate by device due to space constraints. Since this has not been published yet, I do not want to discuss it in much detail here at this time. The paper presents an analysis of total data rate capabilities and you can work out the effects of how the data representation affects effective sampling rate on a per sensor basis.
