EEG2Code_240 data

The data includes single-target training, single-target testing, and multi-target testing data from 18 subjects.

The three files allSubjects_trainonedata.mat, allSubjects_testonedata.mat, and allSubjects_testmultidata.mat contain the single-target training, single-target testing, and multi-target testing data for all subjects, respectively. The data is stored in the file in the form of a struct, where the structure names represent the 18 subjects. And includes data from 1 second before the stimulus to 1 second after the stimulus for each trial. No preprocessing was performed except for a 50Hz notch filter during data acquisition.

The size of the data for each subject in allSubjects_trainonedata.mat is 360x21x3000 , representing 360 trials * 21 channels * 3000 data points (1 second before stimulus, 1 second stimulus, and 1 second after stimulus at a 1000 Hz sampling rate).

The size of the data for each subject in allSubjects_testonedata.mat and allSubjects_testmultidata.mat is 240x21x3000 , representing 240 trials * 21 channels * 3000 data points (1 second before stimulus, 1 second stimulus, and 1 second after stimulus at a 1000 Hz sampling rate). The categories of the stimuli are arranged in order and correspond one-to-one with the sequence in champion_sequencetest.mat.
