Pre-processing pipelines for different offline experiments
are represented in Fig. 1. The base pipeline is selected such that they can easily be used in an online real-time
decoding scheme18. An H-infinity algorithm was used to specifically remove eye blinks, eye motions, amplitude
drifts and recording biases simultaneously23. The parameters of the H-infinity algorithms were kept the same as
the real-time decoding. Peripheral channels were removed as they typically contain many artifactual components.
The signals were then bandpass filtered using a 4th order butterworth filter. Although the frequency range was the
same, this is one of the differences compared to the real-time decoding as the real-time implementation utilized
finite impulse filter and the phase shift was expected. To this point, all processing was done through a MATLAB
script, which is also provided in the open-sourced repository. Additionally, before each experiment, the signals
were z-scored for each channel
