Table 2 Description of the fields contained within the _EEG.mat file structure.
From: Mobile Brain-Body Imaging and Visual Data of Theatrical Actors During Rehearsal and Performance
EEG.setname | Name defined for the dataset |
|---|---|
EEG.filename | Name defined for the file |
EEG.subject | Subject ID according to data records (P01, P02 or P03)) |
EEG.group | Dyad ID according to data records (DyadA, DyadB or DyadC) |
EEG.session | Recording ID according to data records (recording1, recording2, recording3) |
EEG.comments | Name of the original file from which the data was extracted |
EEG.nbchan | Scalar value indicating number of channels used in EEG acquisition. For each subject a total of |
32 channels were used; nevertheless, due to the complexity of the experiment, for some subjects | |
it was necessary to remove 1 or 2 channels. | |
EEG.trials | Number of times the experiment was conducted |
EEG.pnts | Scalar value indicating vector length of each EEG signal acquired by each channel |
EEG.srate | Scalar value indicating sample rate of system (500 Hz) |
EEG.xmin | Start time of the data recording |
EEG.xmax | End time of the data recording |
EEG.times | 1xN vector containing timestamps at each timepoint N for EEG data. |
EEG.data | KxN matrix containing EEG data vector (channels-K) at each time point N (units: microvolts) |
EEG.chanlocs | 1xN vector containing the spatial location of each channel N according to the international 10-20 system |
EEG.ref | Channel referencing to the common average |
