Detecting selection with deep learning

Matteo Fumagalli, June 2022

How to run this activity

The activity on inference of selection using the machine learning approach packaged in the software ImaGene will be run through Jupyter Notebooks. So, just as in the introductory tutorial on Python and Jupyter Notebooks by Hannes Svardal, you will first need to start a Jupyter Notebook on your AWS instance and connect to it.

Connect to the instance using SSH. Use “wpsg” as the username and the usual password. You can do that either through Guacamole in your web browser:

Or you can use SSH from your terminal:

Once connected through SSH:

  • Navigate into the tutorial directory: cd ~/workshop_materials/a14_ImaGene/Tutorials
  • Start a screen session by typing: screen
  • Confirm with the “Return” key
  • Start the conda virtual environment: conda activate ImaGene
  • Start the notebook server: jupyter notebook --no-browser --port=8889
  • The command blocks the terminal. That is normal. Keep it running. You can detach from the screen and get back to a functional terminal by typing “Ctrl + a, d” (first “Ctrl + a”, then “d”)
  • In your local browser, navigate to the web address: (replace XXX with your Amazon instance IP address
  • Then you should see the contents of the folder in which your instance is running.
  • Find the file called workshop.ipynb and click on it. You will be directed to a new tab with the exercise. All instructions and background information about the activity will be given in the Jupyter Notebook.

The instructions to the activity can be viewed on github.
