Hi,
I just got an emotiv epoc headset.
I am trying the python and the c libraries.
In both libraries data is decrypted for 14 sensors.
Has anyone ever looked if the reference electrodes' data can be also read from the usb stream?

Thank you in advance
Best

No you can't. Electric potential (voltage) is measured as a difference between two electrodes. You are recording the electric potential between each electrode and the reference electrodes. It is meaningless to speak of the data recorded 'at the reference electrodes'.
