aamixsh/GENEEG

The raw files contain raw EEG values (.eeg files) for patients, with corresponding:

1. .art files that denote level of artifact at a given time position. 0 -- No noise, 1 and more -- Noise.
2. .evt files that denote external stimulus at a given time position.

There is data for 17 channels: FP1, FP2, F3, F4, F7, F8, C3, C4, P3, P4, O1, O2, T3, T4, FZ, CZ, PZ. So the .eeg and .art files contain 17 space separated columns, while the .evt file contains only 1 column denoting the stimulus.

The .pkl files contain filtered data from patients as a dictionary of numpy arrays which have been artifact filtered (only 0 noise level), and contig length (200 here) chopped.

The dictionary has two keys "wmci" and "wctrl", representing the two classes MCI and Control for the WAVi dataset.

Each element in the dictionary is a list of patients data stored as a list of arrays.
