artscreenEEG is a MATLAB package to perform basic artifact correction and analysis on electroencephalographic (EEG) data. Please see demo/example_steps.m for an example of how to use the basic functions.
This software is intended for users who wish to mitigate the muscle and electrical artifact found in all electroencephalographic (EEG) recordings and perform basic EEG analysis, whether collected from the users' own labs or collected at other locations.
While it is the view of the authors that all EEG recordings contain some amount of artifact and existing software tools can only mitigate this problem, specific analyses (such as band-limited EEG analyses) are more immune to this artifact. See Further Reading for analysis help.
This software should work on any operating system that runs the correct version of MATLAB.
This software works best with MATLAB R2014a or slighly older MATLAB versions. This software works with newer versions of MATLAB however some graphical functions may be slower due to GUI drawing changes made by MathWorks.
The repository can be cloned with
git clone https://github.com/mdnunez/artscreenEEG.git
The repository can also be may download via the Download zip button above.
After downloading/unzipping the repository, users will need to add these functions to the MATLAB path. In MATLAB, add the repository to the PATH with
%Set 'artloc' to full directory path artloc = 'C:\Users\MATLAB\artscreenEEG'; addpath(genpath(artloc));
For a demonstration of useage, run the following. IMPORTANT NOTE: This script will ask your premission to download example EEG data from figshare.com
%Open example script edit example_steps.m; %Run example script example_steps;
