Stream Pre-Recorded Data

Follow these steps to playback recorded data through the MNE Rt Server to MNE Scan.

  • Pass the path to the file you would like to stream via the -f or --file command line argument. For example: mne_rt_server --file ./MNE-sample-data/MEG/sample/ernoise_raw.fif.
  • Alternativley, you can navigate and edit to the FiffSimulation.cfg file manually. Open the mne-cpp\bin\resources\mne_rt_server_plugins\FiffSimulation.cfg with a text editor and insert the path and file name of the fif file which you want to stream. For example: simFile = ./MNE-sample-data/MEG/sample/ernoise_raw.fif
  • Start the mne_rt_server mne-cpp\bin\mne_rt_server
  • Start MNE Scan mne-cpp\bin\mne_scan
  • Select the FiffSimulator plug-in and place it on the plug-in scene.

  • Click on the FiffSimulator plug-in and select the Connection tab. If you have started the mne_rt_server on your local machine, use IP 127.0.0.1 and press Connect. The status should change to Connected.
  • Click on the FiffSimulator plug-in and select the Preferences tab. We recommend to use the same block size as the sampling frequency. This way the data will be refreshed every second. 

  • Press the green play button in the left upper corner.

  • If you click on the FiffSimulator plug-in you should now see the real-time data display.
