Are you setting up an experiment with a mobile EEG device and you want to send triggers via Presentation? You can do it completely wirelessly and without much effort. In this short blog, we describe how to send triggers using LSL and mbt Streamer.
You can simply Enable sending LSL triggers from the General Settings of Presentation, to send a LSL stream called “Presentation” to any other app on the same computer, or any other device on the network.
The LSL stream will be automatically detected in the mbt Streamer, and can be recorded all into one .xdf file, as the LSL LabRecorder does. However, mbt Streamer can do much more, as it can integrate keyboard presses as markers, and include 3D head motion visualizations etc.
Then you can open the .xdf file with Python or Matlab and analyze the data.
