Phase information from FFT plot/Networking

Hello!
Is there any way to access the phase information from the FFT calculation within the OpenBCI_GUI? If so, how? The FFTplot/Networking widgets are much more efficient than anything I have been able to write on my own in python, but I would like to use the phase information in addition to the power if that is possible.

JStieger, hi.
You could use the Networking widget to send LSL to OpenViBE, then use their Spectral Analysis box. It can output amplitude, phase, real, and imaginary components. These could then be routed out via LSL or sent to a recording file.

Thanks William!
Any chance you have a mac friendly solution?
Some people use a VM,

I would recommend sending FFT data over LSL to Python. For now, I think we need to set the #Chan textfield to 125 for Cyton+Daisy. Then, you can process the phase information in Python.
