 ## Andrea Brovelli: Neuronal Interactions
 The folder `tutorials/notebooks` contains a series of 5 exercises based on the Frites software package, which are replicated from https://github.com/brainets/CookingFrites.
 Part 0 explains the usage of `xarray`, a Python package used to represent data in Frites. Tutorials 1-4 then cover the various stages of a Frites workflow based on an example sEEG dataset.
