DATA & FILE OVERVIEW


File List:
The files contain the raw data, scripts, and results of main and supplementary analyses of the electroencephalography (EEG) study. Links to the hardware and software are provided under methodological information.


AAN3_experiment_scripts.zip: contains the Python files to run the experiment


AAN3_rawdata_EEG.zip: contains raw EEG data files for each subject in .bdf format (generated by Biosemi)


AAN3_rawdata_log.zip: contains log files of the EEG session (generated by Python)


AAN3_EEG_scripts.zip: Python-MNE scripts to process and to analyze the EEG data


AAN3_EEG_source_localization_scripts.zip: Python-MNE files needed for source localization. The template MRI is provided in this zip. The files are obtained from the MNE tutorial (https://mne.tools/stable/auto_tutorials/source-modeling/plot_eeg_no_mri.html?highlight=template). Note that the stc folder is empty. The source time course files are not provided because of their large size. They can quickly be generated from the analysis script. They are needed for the source localization.


AAN3_analysis_scripts.zip: R scripts to analyze the data. The main file is performance_correction.html. It contains the results of the main analyses.


AAN3_results.zip: contains summary data files, figures, and tables that are created by Python-MNE and R.


METHODOLOGICAL INFORMATION


1. Description of methods used for collection/generation of data:
The auditory stimuli were two 100-ms tones (f = 900 Hz and 1400 Hz, 5 ms fade-in and fade-out).
The experiment was programmed in Python: https://www.python.org/ and used extra functions from here: https://github.com/stamnosslin/mn
The EEG data were recorded with an Active Two BioSemi system (BioSemi, Amsterdam, Netherlands; www.biosemi.com) and saved in .bdf format.
For more information, see linked publication.


2. Methods for processing the data:
We computed event-related potentials and source localization. See linked publication


3. Instrument- or software-specific information needed to interpret the data:
MNE-Python (Gramfort A., et al., 2013): https://mne.tools/stable/index.html#
Rstudio used with R (R Core Team, 2016): https://rstudio.com/products/rstudio/
Wiens, S. (2017). Aladins Bayes Factor in R (Version 3). https://www.doi.org/10.17045/sthlmuni.4981154.v3


4. Standards and calibration information, if appropriate:

5. Environmental/experimental conditions:

6. Describe any quality-assurance procedures performed on the data:

7. People involved with sample collection, processing, analysis and/or submission:


- Data collection: Rasmus Eklund with assistance from Billy Gerdfeldter.
- Data processing, analysis, and submission: Rasmus Eklund and Stefan Wiens


DATA-SPECIFIC INFORMATION:
All relevant information can be found in the MNE-Python and R scripts (in EEG_scripts and analysis_scripts folders) that process the raw data. For example, we added notes to explain what different variables mean.


The folder structure needs to be as follows:
AAN3 (main folder)
--->data
--->--->bdf (AAN3_rawdata_EEG)
--->--->log (AAN3_rawdata_log)
--->--->raw (empty)
--->MNE (AAN3_EEG_scripts)
--->R (AAN3_analysis_scripts)
--->results (AAN3_results)
--->source (AAN3_EEG_source_localization_files)


To run the MNE-Python scripts:
Anaconda was used with MNE-Python 0.20 (see installation at https://mne.tools/stable/index.html# ).
For Downsample_AAN3, ICA_raw_AAN3, Preprocess_AAN3, Make_inverse_operator_AAN3.py, BehaviorTables_AAN3, and PlotSource, the complete scripts should be run (from anaconda prompt).
For Analysis_AAN3, one section at the time should be run (from Spyder).
