Pybrain 2020: M/EEG analysis with MNE-Python

Preparations

To participate in the workshop, you will need to set up a Python environment with a number of dependencies. The following instructions will guide you through the process.

The notebooks will be made available in this GitHub repository at the beginning of the workshop.

Download & install Anaconda

We will work with the Anaconda Python distribution.

Install MNE-Python

Open an Anaconda prompt
Follow the MNE-Python installation instructions for your operating system
Activate your newly-installed MNE-Python environment by typing into the Anaconda prompt:
```
conda activate mne
```

Verify your MNE-Python installation by running in the Anaconda prompt:

mne sys_info

The output should look similar to the following:

  Platform:      macOS-10.15.7-x86_64-i386-64bit
  Python:        3.8.5 (default, Sep  4 2020, 02:22:02)  [Clang 10.0.0 ]
  Executable:    /Users/richard/miniconda3/envs/mne-new/bin/python
  CPU:           i386: 4 cores
  Memory:        8.0 GB

  mne:           0.21.1
  numpy:         1.19.2 {blas=mkl_rt, lapack=mkl_rt}
  scipy:         1.5.2
  matplotlib:    3.3.2 {backend=MacOSX}

  sklearn:       0.23.2
  numba:         0.51.2
  nibabel:       3.2.0
  cupy:          Not found
  pandas:        1.1.3
  dipy:          1.3.0
  mayavi:        4.7.2
  pyvista:       0.27.2 {pyvistaqt=0.2.0, OpenGL 4.1 INTEL-14.7.8 via Intel HD Graphics 5000 OpenGL Engine}
  vtk:           9.0.1
  PyQt5:         5.13.2

Install JupyterLab

We will use the Jupyter Lab environment to run our workshop notebooks. Inside the Anaconda prompt, run:

conda activate mne
conda install -y jupyterlab

Then, run:

jupyter lab

If the installation was successful, your browser should open. You may close it again, and stop the JupyterLab process in the Anaconda prompt by pressing the keys Ctrl and C simultaneously and then enterying y when asked if you're sure.

Install MNE-BIDS

To readand write BIDS data, we will use MNE-BIDS. To install it, run the following commands inside the Anaconda prompt:

conda activate mne
pip install mne-bids nibabel pybv

Download MNE-Python sample data

We will work with some sample data that can be easily retrieved via MNE-Python. Open an Anaconda prompt and run:

conda activate mne
python -c "import mne; mne.datasets.sample.data_path()"

This will retrieve about 1.5 GB of data, so it might take a while if your internet connection is slow.

Workshop summary

The workshop will cover a broad range of topics to help you get to know all essential parts of MNE-Python for conducting MEG and EEG data analysis:

loading, filtering, and inspecting raw data
working with BIDS data
epoching and artifact correction
creating and visualizing evoked responses (ERP / ERF)
contrasting evoked responses of different experimental conditions
decoding neural responses (machine learning)
performing time-frequency analysis
estimating and visualizing cortical sources (source localization)
conducting a group analysis

We will start with a 30 min warm-up at 9:00 a.m. UTC on both days. During this warm-up, we can resolve technical difficulties you might be experiencing. The actual workshop will start at 9:30.

Lunch break is from 12 to 1, and we will continue until 3:30 or longer if need be (to hopefully address all open questions).
