# Source EEG data info
## Data directory structure
Source EEG data of the 10 participants. In each `.zip` file the source EEG data is divided into the four recording sessions and into 'eeg' (EEG data as returned by the EEG recording software) and 'beh' (behavioral data, as returned by the MATLAB presentation program). For each session, the data consists of two resting state data files (one collected at the beginning of the session, and one at the end), one test images presentation partition, and five training images presentation partitions:

You can also download the source EEG data directly from [Google Drive][drive].
We used [this code][github] to convert the source data into raw data.
