Hi all, I would like to use MatLab + BCILAB to pre-process, classify, and visualize real-time EEG data from OpenBCI.

https://github.com/sccn/labstreaminglayer/wiki/SupportedDevices.wiki

I uploaded some screenshots taken when OBCI is outputting via LSL (i.e. http://docs.openbci.com/software/06-labstreaminglayer ): http://imgur.com/a/gNAqn

Use the search box at lower right for LabStreamingLayer. By outputting a named stream it should be possible to send to any number of LSL input devices. While OpenBCI_GUI does not currently consume LSL

Use the search box at lower right for LabStreamingLayer if you want to distribute the same EEG data stream to mulitple laptops. It handles distribution as well as timing synchronization.

Try searching on the following terms (search box lower right column) for other software packages that can process OpenBCI data: neuromore, BrainBay, BioEra, OpenViBE, LabStreamingLayer, Python, MATLAB

The LSL LabStreamingLayer might help you synchronize streams, but there may still be substantial jitter since the sample rate clocks are not crystal controlled. Thus sample rate can vary, e.g 250 sps,

Thanks, Jfrey!  That worked for me, and I posted a walk-thru here:http://openbci.com/forum/index.php?p=/discussion/615/labstreaminglayer-lsl-stream-from-openbci-here-s-how

* Download the LSL Python library:  https://github.com/sccn/labstreaminglayer/tree/master/LSL/liblsl-Python. You may have to download the .zip of the whole project from here: https://github.com/sccn/l

But still the LSL repo itself doesn't have any OpenBCI app within it: https://github.com/sccn/labstreaminglayer/tree/master/Apps

Drift is important if you are synchronizing multiple realtime data streams, as is common in BCI. LabStreamingLayer can also be a part of the solution in these cases.

@Mike , let's mention Joel @biomurph , and ask for his tips on how the accelerometer values are interpolated into the stream. Your current heuristic of checking for all zeros sounds just fine to me. D
