four channels of data with a cyton board rather than a ganglion board?

Hello, I am a high school student in Korea who is doing research on EEG.
There is little information about OpenBCI in Korea, so I asked this question.

How should I connect the pins to get 8 channel data using the cyton board?
And, can I accurately measure 4-channel data with a cyton board rather than a ganglion board?

Thank you

    You can use Cyton with any number of channels from one to all eight. Similar idea with Ganglion, 1, 2, 3 or 4 channels at once.

    I know that I can turn off a channel by pressing a button in the GUI.
    But I get data through python code instead of GUI.
    How to get 4 channel data with python code?

    You can just IGNORE the channels you do not use in your Python / Brainflow code.

    OR (not necessary to do this), you can actually turn off the unused channels using the SDK commands,

    No advantage in turning the channels off. In the GUI turning channels off reduces the operator distraction factor from unused 'noisy' channels. But with your Python no one sees the unused channel data.
