rERP	EEG visualisation	EEG Simulations	BIDS pipeline	Decode EEG data	Statistical testing

A toolbox for visualizations of EEG/ERP data and Unfold.jl models.

Based on three libraries

• Unfold - for performing deconvolution regression;
• Makie - very flexible visualisation library (Maki-e means "visualisation" on Japanese);
• Algebra of Graphics - Makie-based visualisation library, allowing flexible mapping.

This grants users high performance, and highly customizable plots.

We currently support 9 general ERP plots:

• ERP plots
• Butterfly plots
• Topography plots
• Topography time series
• ERP grid
• ERP images
• Channel images
• Parallel coordinates
• Circular topoplots

And 2 Unfold-specific plots:

• Design matrices
• Splines plot

Install

Installing Julia

Click to expand

The recommended way to install julia is juliaup. It allows you to, e.g., easily update Julia at a later point, but also to test out alpha/beta versions etc.

TLDR: If you don't want to read the explicit instructions, just copy the following command

Windows

AppStore -> JuliaUp, or winget install julia -s msstore in CMD

Mac & Linux

curl -fsSL https://install.julialang.org | sh in any shell

Installing UnfoldMakie.jl

using Pkg
Pkg.add("UnfoldMakie")

Quickstart

using UnfoldMakie
using CairoMakie # backend
using Unfold, UnfoldSim # Fit / Simulation

data, evts = UnfoldSim.predef_eeg(; noiselevel = 12, return_epoched = true)
data = reshape(data, 1, size(data)...) # simulate a single channel

times = range(0, step = 1 / 100, length = size(data, 2))
m = fit(UnfoldModel, @formula(0 ~ 1 + condition), evts, data, times)

plot_erp(coeftable(m))

Contributions

Contributions are very welcome. These can be typos, bug reports, feature requests, speed improvements, new solvers, better code, better documentation.

How to Contribute

You are very welcome to submit issues and start pull requests!

Adding Documentation

1. We recommend to write a Literate.jl document and place it in docs/literate/FOLDER/FILENAME.jl with FOLDER being HowTo, Explanation, Tutorial or Reference (recommended reading on the 4 categories).
2. Literate.jl converts the .jl file to a .md automatically and places it in docs/src/generated/FOLDER/FILENAME.md.
3. Edit make.jl with a reference to docs/src/generated/FOLDER/FILENAME.md.
