Order of data for Cyton Daisy (16 Channels)

Hi Community,
I have logged the OpenBCI (Cyton and Daisy board) data, which has 16 channels. Yet, it gave me 19 columns I believe. Could anyone give me a hint what is the order of this column? I tried to look for it in this forum but could not find it. Your answer will help me out in giving labels to my EEG data.
Thanks a lot

    Ihgumilar, hi.

    Cyton includes 3 additional 'channels' for 'Aux data'. By default this represents the onboard accelerometer. But can also be switched to sample 0V to 3.3V analog or digital data.

  • Hi William,
    Thanks for the additional information. Does it mean accelerometer data?
    Could you let me know the order of labels including the accelerometer data?
    I still cannot find it on the link that you gave me.

    It's in the section 'Binary Format' at that link. For accel, order is X, Y, Z.

  • Thanks. I found the following info
    Bytes 3-5: Data value for EEG channel 1.......****What is the label for channel 1 and so on ?****
    Bytes 6-8: Data value for EEG channel 2
    Bytes 9-11: Data value for EEG channel 3
    Bytes 12-14: Data value for EEG channel 4
    Bytes 15-17: Data value for EEG channel 5
    Bytes 18-20: Data value for EEG channel 6
    Bytes 21-23: Data value for EEG channel 6
    Bytes 24-26: Data value for EEG channel 8

    The page link I gave just shows the channel / data ordering. If you are using the GUI CSV, the data has already been assembled and scaled. Bytes shown are just the raw binary data from the ADS1299 and firmware.
