Cognionics
I recorded some data from the Cognionics and sent it in real-time to OpenVibe via LSL. From OpenVibe I am are recording data from 3 channels at 500 Hz. However I am getting this type of signal in the time domain (image below) which has repeated values. Did anyone encounter same problem?

Re: Cognionics
Hi Rosanne,
we don't have Cognionics here in the lab to test, but here's a few things might help to debug the problem,
1) Are you able to read data from Cognionics successfully with some other software via LSL?
2) The plot you show is made outside openvibe. Do you see the same kind of behaviour if you
use the signal display box to show the signal in designer in real time?
3) Did you have Drift Correction disabled in Acquisition Server? (try Disabled)
And finally, are you doing things in this order:
Cognionics -> LSL -> Acquisition Server -> OpenViBE Designer -> write to file (which format?) -> plot in some other software (which)?
or something else?
Cheers,
Jussi
