LSL Export Neurofeedback

[arayes2000]

Dear Friends,
Good afternoon. I am trying to view the output signal stream for the BCI Neurofeedback example on Matlab LSL viewer, however the is no signal shown in the LSL viewer. I could only view oscillating signals (before averaging the signal). Should I change the stream type for EEG to another stream type, and if so which stream type should I use? If not, how could I stream the final output neurofeedback signal?

Thank you.
