MEEGbuddy 0.0.dev0

Workflow objects for MEG (not yet) and EEG data processing

# MEEGbuddy

I work in a lab that analyzes many psychphysical tasks with the same structure: there are trials with stimuli and responses. If this matches the description of what you’re studying, this tool will probably be very helpful. Using MEEGbuddy, I was able to preprocess ~70 subjects for three tasks using both MEG and EEG in three days not counting computation time.

MEEGbuddy uses MNE, autoreject and PCI (noreun on github) for preprocessing mostly but also analysis of MEEG data. TFR psd multitapers, including sleep scoring, and morlet are supported as well as cluster permutation tests and lempel-ziv complexity (connectivity coming soon hopefully). These preprocessing and analysis steps all come with defaults that will run well as is and have lots of the kinks figured out already with the added bonus that they are saved in BIDS structure (or pretty close).



## Installation Instructions First install anaconda (recommended) (https://www.anaconda.com/distribution/#download-section) or your manage your own python (https://www.python.org/downloads/). For this to work properly, you have to be able to run “python” and “pip” from a terminal. To have a terminal recognize python, if it doesn’t automatically after install, you have to add python to the path. In MacOS or Linux you can modify the .bash_profile/.bashrc (for terminals with $) or the .cshrc (terminals that end with [1]) by adding “alias python=’python3’ “ and “alias pip=’pip3’ “ if you used anaconda or “alias python=’/path/to/bin/python3’ “ and “alias pip=’/path/to/bin/pip3’ “. For Windows, it’s a little tricker. Find the “Environment Variables” settings window, I would recommend just searching but it should be under Properties>System Properties>Advanced. Then add to the path both the /path/to/python and the /path/to/pip which likely is a subdirectory in the python folder (subdirectories do not get added automatically). (Note: run “…” means type “…” into a terminal)

0. Optional preinstallation for making a virtual environment so you don’t break dependancies in other python programs you use 0a. run “pip install virtualenv –user” 0b. run “virtualenv /Path/to/where/you/want/to/store/your/venv” 0c. run “source /Path/to/where/you/want/to/store/your/venv/bin/activate” 1. run “pip install MEEGbuddy” 2. run “pip install -r requirements.txt” 3. (Optional) Install freesurfer (https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall) 4. (Optional) Add “alias mb ‘cd /Path/to/MEEGbuddyDemo/or/your/project; source /Path/to/where/you/want/to/store/your/venv/bin/activate; export FREESURFER_HOME=/Path/to/freesurfer; source $FREESURFER_HOME/SetUpFreeSurfer.sh’ “ so that you can type “mb” into a terminal to activate your project. Note you need to have installed freesurfer for the last two commands in the alias (export … and source $FREESURFER…)

To run the demo: 1. install jupyter if you haven’t already: run “pip install jupyter” 2. install dependencies if you haven’t already: run “pip install -r requirements.txt” OR run “pip install pandas mne scipy autoreject seaborn matplotlib tqdm joblib nitime pysurfer naturalneighbor mayavi” 3. run “jupyter notebook”

This was originally designed in python2 but now is only supported in python3
