ANDA-NI Tutorials 2024

Udo Ernst: Spectral Analysis

Instructions for the exercises are provided in the file ANDA2024_Training_Spectral.pdf.

Exercises for individual methods are contained in the test-* files. The second part of the exercise is contained in the notebook ANDA2024_Spectral_DataAnalysis.ipynb.

To get started, create a Python environment using the environment.yml file provided.

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. Information on the various stages of the workflow, and on the dataset details are located in the folder tutorials/slides.html. Each tutorial goes through a sequence of processing steps on the example datasets, and ends on a practical exercise to explore the dataset further.

Byron Yu: Dimensionality Reduction

The notebook tutorials/Exercise_PCA.ipynb contains a the primary exercise centered around implementing a simple principle component analysis (PCA). Also, in tutorials/Tutorial_GPFA.ipynb you will find a tutorial guiding you through the application of the GPFA implementation of Elephant on an example dataset. For this tutorial, a video tutorial is available (see link in notebook).

The notebook tutorials/Exercise_PCA_to_FA.ipynb contains a mathematically more advanced exercise covering both PCA and the transition to Factor Analysis (FA).

To get started, create a Python environment using the environment.yml file provided.

Martin Nawrot: Higher-order Correlations

The notebook tutorials/trial_by_trial_variability.ipynb contains an exercise centered around time-resolved Fano Factors. The first lines of the exercises contain code that help you load the used datasets.

To get started, create a Python environment using the environment.yml file provided.

Sonja Grün: Higher-order Correlations

The folder tutorials contains a series of 4 exercise notebooks. Exercise 0 should be considered more of a warm-up exercise, and exercises 1-3 cover cross-correlations, Unitary Event Analysis and higher-order correlations,respectively. The notebooks contain working exercise codes and additional tasks that build on the provided code.

To get started, create a Python environment using the environment.yml file provided.
