Description of the dataset follows below.

meg: MEG and source localization files within a folder for each subject
Note: subject R2667 left the MEG dewar mid-experiment and therefore has two head position measurements. R26672 folder has data from subject R2667 for the second part of the experiment with the approprate source localization files.

Each subject folder contains following files
- subject_visit_task-raw.fif
	preprocessed raw fif files for each visit and task (200 Hz sampling rate)
	Maxwell filtering (tsss), 1-40 Hz bandpass filtering and ICA for artifact rejection have been applied
- subject_visit_task-cov.fif
	Noise covariance estimated from emptyroom data for source localization.
- subject_visit_task_tstart.pkl
	time of trial start
- subject_visit_task_triggers.csv
    trigger information used to extract epochs
- MRI scaling parameters.cfg
    the scaling transform from subject to fsaverage. 
- subject_visit_task-fwd.fif
    forward solution for source localization
