Magnetoencephalography recordings on newborns with auditory stimulations

This dataset is organized in 3 main folders:1. The folder 'data' contains the magnetoencephalography (MEG) recording data, organized in a BIDS-like structure: first by subjects and then by modalities. The optically pumped magnetometers (OPM) data folders contains the raw data and the preprocessing output files. The cryogenic MEG (SQUID) data folders contain the data after signal space separation (using MaxFilter) and the preprocessing output files.The MEG files contain a time variable (time), a MEG data variable (data_meg), a sampling frequency variable (sfreq) and a variable containing the time stamps of the stimulations (trials). The OPM data in addition has an OPM position on the layout variable (positions) and a OPM labels variable (labels).The preprocessing output files contain a variable with the artifact time stamps (bad_times) and a variable containing the heart and artifact component of an independent component analysis (ICA). If a second ICA was performed, another variable is present (IC). When computed, the frequency ranges of those components is also included (freq2. The folder 'layouts' contains the layouts files needed for the analysis.3. The folder 'derivatives' contains the derivative data obtained by the analysis scripts which are the data used for generating the plots in the article.All the files are in the Matlab matrix file format ('.mat').
