Dev CI License: MIT Julia 1.12+ Status: Alpha
A Julia package for EEG/ERP data analysis and visualization. Currently under active development.
The documentation includes:
- Installation instructions and getting started guide
- Tutorials and Demos
- Complete API reference
You can install EegFun.jl through the standard Julia package manager.
From the Julia REPL, enter Pkg mode by pressing ] and run:
add EegFun
Or using Pkg in the code:
using Pkg Pkg.add("EegFun")
To install the latest development version directly from GitHub:
using Pkg Pkg.add(url="https://github.com/igmmgi/EegFun.jl")
- EEG/ERP Analysis
- EEG/ERP Interactive Plots (via Makie.jl)
- Time-Frequency Analysis
- Raw data to full ERP batch preprocessing pipelines
