Denoising tools for M/EEG processing in Python 3.7+.
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.
Automatic documentation is available online.
This code can also be tested directly from your browser using Binder, by clicking on the binder badge above.
This package can be installed easily using pip+git:
pip install git+https://github.com/nbara/python-meegkit.gitOr you can clone this repository and run the following commands inside the python-meegkit directory:
pip install -r requirements.txt
pip install .Note : Use developer mode with the -e flag (pip install -e .) to be able to modify the sources even after install.
Some ASR variants require additional dependencies such as pymanopt. To install meegkit with these optional packages, use:
pip install -e '.[extra]'or:
pip install git+https://github.com/nbara/python-meegkit.git#egg=meegkit[extra]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, ZapLine and robust detrending have been properly tested so far. TSCPA may give inaccurate results due to insufficient testing (contributions welcome!)
