UNFOLD - TOOLBOX

A toolbox for deconvolution of overlapping EEG signals and (non)-linear modeling

Linear deconvolution
Model specification using R-style formulas (EEG~1+face+age)
Programmed in a modular fashion
Spline regression
Regularization (using glmnet)
Temporal basis functions (Fourier & Splines)
Estimate temporal response functions (TRFs) for time-continuous predictors
Cross-validation

Installation

git clone https://github.com/unfoldtoolbox/unfold
git submodule update --init --recursive --remote

Running

run('init_unfold.m')

Simple example

Check out the toolbox tutorials for more information!

EEG = tutorial_simulate_data('2x2')
EEG = uf_designmat(EEG,'eventtypes',{'fixation'},'formula','y ~ 1+ cat(stimulusType)*cat(color)')
EEG = uf_timeexpandDesignmat(EEG,'timelimits',[-0.5 1])
EEG = uf_glmfit(EEG)
% (strictly speaking optional, but recommended)
ufresult = uf_condense(EEG)
ax = uf_plotParam(ufresult,'channel',1);
