%% HFO detection
% This function prepares data file from simulation.
% (1) load dataset with basic pre-processing
% (2) setup electrode file (containing channel information)
%
% Note that the dataset contains raw spike epochs simulated from realistic
% clinical dataset. The attached simulation data consists of epoched spikes
% with additive HFOs and artifacts, embeded in white or realistic EEG background
% noise of SNR at 5~20dB. The noise data is modeled from white Gaussian
% process and real clinical recordings using autoregressive model.
% The electrode file contains the digitizer of the surface channels, which
% defines the sequence, the name, and the 3D location in the scalp, which
% will be used for visualization purposes.
