FREQUENTLY ASKED QUESTIONS

How do I load CSV data from Unicorn BCI Core Recorder into MATLAB?

An import script is provided:

  1. Add the folder C:\Users\<username>\Documents\gtec\Unicorn\BCI Core\Unicorn BCI Core Recorder\MATLAB Tools to your MATLAB search path.
  2. Use the command: data = unicornrecorder_read(‘filename.csv’);

This will import the data and associated metadata into MATLAB.

What file formats can I use to save recorded data using Unicorn BCI Core Recorder?

You can save recorded data in CSV or BDF+ file formats. These settings can be adjusted in the Recording Settings dialog.

How do I configure network settings for sending or receiving data?

You can configure network settings under the Network Settings section. This includes:

  • Receiving triggers via UDP: Set IP and Port (default IP: 127.0.0.1, Port: 1000).
  • Sending data via UDP: Default IP is 127.0.0.1, and the port is 1001.
  • Sending data via LSL: Modify the default LSL stream name (UnicornRecorderLSLStream) as needed.

How do I use triggers with Unicorn BCI Core Recorder?

Triggers can be sent to the recorder via UDP from external applications, like stimulus presentation tools. Ensure the UDP port is correctly configured and not conflicting with other settings.

Can I send data from Unicorn BCI Core Recorder to an external application in real time?

Yes, you can send data using:

  • UDP: Configure the IP and Port settings in Network Settings.
  • LSL: Modify the LSL stream name and use compatible applications to receive the data.

How can I verify the signal quality of the EEG data from my Unicorn BCI Core-4 Headband?

The Signal Quality Indicators monitor the quality of the EEG signal. The raw EEG is filtered to observe amplitude variations. Electrodes will turn green if the signal is within the proper range and red if the quality is poor.

What are the default filter settings for signal processing?

Predefined IIR filters available include:

  • Bandpass filters (e.g., 0.1–30 Hz, 0.5–50 Hz)
  • Highpass filters (e.g., >0.1 Hz, >2 Hz)
  • Lowpass filters (e.g., <20 Hz, <50 Hz)
  • Notch filters to remove power line noise (50 Hz, 60 Hz, or both).

What should I do if my data acquisition is not starting?

Ensure the Unicorn BCI Core-4 Headband is connected and recognized in the Connection dialog. Use the Start/Stop Acquisition button on the Control Bar to initiate data acquisition.

How do I connect my Unicorn BCI Core-4 Headband device to the Unicorn BCI Core Recorder?

When you open the Unicorn BCI Core Recorder, a Connection dialog will appear. Turn on your Unicorn BCI Core-4 Headband , wait for it to be discovered, select it, and click the Connect button.

How do I install the Unicorn BCI Core Recorder?

To install the Unicorn BCI Core Recorder, ensure you have g.tec Suite 2024 (version 1.24.01 or later) installed along with the latest update. Please note that the g.tec Suite 2024 must be purchased separately. However, if you already have a g.tec Suite 2024 license, there is no need to purchase it again.

What should I do if the Unicorn BCI Core-4 Headband does not turn on?
