Look inside

In this liveProject, you’ll help find a cure for a (fictional) global pandemic by identifying the origin of the virus. Biologists have already narrowed the list of suspects down to three animal species. Longest Common Subsequences (LCS) can help you measure the similarity between two sequences. You'll use them to compare the animal sequences with the virus’ sequence. You'll get a sense of what percentage of the sequences should be common versus what is actually common between the sequences studied, then you'll be able to identify the virus’ origin based on your findings.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.

project author

Joris Limonier
Joris Limonier has worked at the Unit of Research in Computer Science at the University of Luxembourg and has a strong background in Julia, Python for data science, LaTeX, and Swift. He’s earned degrees in mathematics, data science, and artificial intelligence. To share his passion for Julia, he creates Julia content including YouTube videos and open-source projects on GitHub.


The liveProject is for intermediate Julia programmers with experience plotting data. To begin these liveProjects you'll need to be familiar with the following:

  • Jupyter notebook or Notebooks in VS Code
  • Plots.jl for basic plotting
  • CSV.jl to import data from csv files
  • DataFrames.jl to exploit your data
  • Basic mathematics and statistics (mathematical operations, logical reasoning)
  • Basics of programming (data structures, arrays, dictionaries, loops, functions)
  • Basics of data science (how to start with data, apply scientific reasoning and draw conclusions)

you will learn

In this liveProject, you’ll learn the basics of LCS and how to use them to identify outliers.

  • Make simulations to compute “normal” LCS and identify outliers
  • Determine how much is in common between each of the sequences from the outliers Draw conclusions from plots


You choose the schedule and decide how much time to invest as you build your project.
