The present package contains MATLAB code assessing the acoustic contamination of neural recordings, as well as an example dataset. It refers to the following article: Roussel et al 2020 J. Neural Eng. https://doi.org/10.1088/1741-2552/abb25e Please cite this article in publications using this package. REQUIREMENTS The scripts in this package require MATLAB R2018b or a more recent release. CONTENT The "Data" directory contains an example dataset recorded using a microphone and a neural recording system connected to an electrocorticography electrode grid immersed in a saline solution. The files are formatted as MAT-files with a defined structure. The "Toolbox" directory contains a MATLAB class named ContaminationAnalysis designed to perform the analysis of potential acoustic contamination. The public methods of this class allow to compute the analyses, store the produced data and display the results. The "functions" subfolder contains MATLAB functions that are used in the ContaminationAnalysis class and/or in the scripts featured in this package. The "Scripts" directory contains two MATLAB scripts. "data_formatting_example_script" shows how to format the data before analyzing it. "analysis_example_script" shows how to use the ContaminationAnalysis class to carry out the analyses.
