MEEGkit: M/EEG processing toolkit in Python 🧠🔧

MEEGkit

Denoising tools for M/EEG processing in Python 3.5+.

Disclaimer: The project mostly consists of development code, although some modules and functions are already working. Bugs and performance problems are to be expected, so use at your own risk. More tests and improvements will be added in the future. Comments and suggestions are welcome.

This code can be tested directly from your browser using Binder, by clicking on the binder badge above.

Installation

This package can be installed easily using pip+git:

pip install git+https://github.com/nbara/python-meegkit.git

Or you can clone this repository and run the following command inside the python-meegkit directory:

pip install .

Note : Use developer mode with the -e flag (pip install -e .) to be able to modify the sources even after install.

Python implementation of CCA, STAR, SNS, DSS, and robust detrending

This is mostly a translation of Matlab code from the NoiseTools toolbox by Alain de Cheveigné. It builds on an initial python implementation by Pedro Alcocer.

Only CCA, SNS, DSS, STAR and robust detrending have been properly tested so far. ZapLine and TSCPA may give inaccurate results due to insufficient testing (contributions welcome!)
