Just a quick question, can I playback bdf files in OpenBCI gui ？
@Sixian GUI can only playback CSV files in the "OpenBCI Data Format" at this time (5.0.4).
I have used EDF Browser to check the data saved from the GUI. https://www.teuniz.net/edfbrowser/
I think it's worth considering developing this as a new feature, given that we are publicly discussing how to improve saved data from the GUI. The BIDS format also approves of the EDF/BDF format, as it is used by many labs worldwide.
Sixian, as Richard mentioned EDFBrowser is a valuable utility. It also has the ability to 'convert' file formats. So you could use the default GUI CSV format to allow playback in the GUI. Then use EDFBrowser to convert your CSV file to BDF if needed.
