Logging of widget values

in OpenBCI_GUI
Hi,

I can see how to log raw data directly from the headset channels, but is it possible to log the widget values to a timestamped file?
I specifically would like to record the band data, heart rate and focus over time.

I understand that this can be generated via matlab or similar, but since they have already been calculated via the widgets I was hoping for a simpler option.

Any advice gratefully received!

Thanks
Duncan

    Duncan, hi.

    Have you looked at the Networking Widget in the GUI? It allows you to output data streams in various standard formats: OSC, LSL, UDP, Serial. You can then select what stream you are putting in each position: Time Series, FFT, EMG, Band Power, Focus, Pulse.

    With a receiver for say LSL or OSC, you could then record the stream to a file, or use it in some other type of feedback / process. 

    For more on LSL see,

    [for example you could write a short Python program that receives a stream, then stores to a file.]

    Additionally, if you wanted the GUI to record files directly from these widget sources, you could always add code to the W_ widget source files,


    Regards,

    William

    Timestamps will be coming to LSL streaming via Networking Widget very soon!
