A toolbox for deconvolution of overlapping EEG (Pupil, LFP etc.) signals and (non)-linear modeling
New in 1.2 (December 2020): More automatic cleaning tools (ASR, Entropy-Based). Many Bugfixes, better Documentation and better error-codes.
We recently published a new preprint on the analysis of Eyetracking/EEG data, with unfold playing a prominent role Dimigen & Ehinger 2019

Adjust for overlap between subsequent potentials using linear deconvolution
Massive-Univarite Modeling (rERP) using R-style formulas, e.g.
Non-linear effects using regression splines (GAM), e.g.
Model multiple events, e.g. Stimulus, Response and Fixation
Use temporal basis functions (Fourier & Splines)
(Optional) regularization using glmnet
Temporal Response Functions (TRFs)
We are developing a sister-toolbox for Julia. It is not feature-par with matlab-unfold yet, e.g. splines are missing and no plotting tools. But it allows to specify more flexible basisfunctions, e.g. different types for different events and different lengths. It also fully supports MixedModels (but that part is still untested in practice, besides unittests).
(deprecated) The addon unmixed, allowing to use mixed models can be found in its alpha version version here
