Data preprocessing: question

[neurohazardous]

Thanks for sharing this data, this is great! I have a quick question: is the data shared here raw? Has it been preprocessed in any way?

Thanks for your time!

Sorry for the late reply. The amplitude are raw data. But phase are calibrated using below code.

function calibrated_phase2 = phase_calibration(phasedata)
    calibrated_phase(1) = phasedata(1);
    difference = 0;
    for i = 2:30
        temp = phasedata(i) - phasedata(i-1);
        if abs(temp) > pi
            difference = difference + 1*sign(temp);
        end
        calibrated_phase(i) = phasedata(i) - difference * 2 * pi;
    end
    
    k = (calibrated_phase(30) - calibrated_phase(1)) / (30 - 1);
    b = mean(calibrated_phase);
    
    for i = 1:30
        calibrated_phase2(i) = calibrated_phase(i) - k * i - b;
    end
end
