This is a draft version, we are very happy to receive comments and criticism (info@unfoldtoolbox.org)

Why deconvolution and non-linear modeling?

Find a twitter thread explaining the general idea here or have a look at Figure 1 of our paper

What can you do with unfold?

  • Adjust for overlap between subsequent potentials using linear deconvolution
  • Massive-Univarite Modeling (rERP) using R-style formulas, e.g. EEG~1+face+age
  • Non-linear effects using regression splines (GAM), e.g. EEG~1+face+spl(age,10)
  • Model multiple events, e.g. Stimulus, Response and Fixation
  • Use temporal basis functions (Fourier & Splines)
  • (Optional) regularization using glmnet
