Usage of NGS is increasing in several biological fields due to a very rapid decrease in cost. However, it often results in hundreds of Gbs of data making the downstream analysis very challenging and requires bioinformatics skills.

In this module, we will introduce the most used sequencing technologies and explain their decryption concepts.

We will also introduce the repositories e.g. the European Nucleotide Archive (ENA), Sequence Read Archive (SRA) from which you could retrieve raw data based on specific experiments. We will practice the usage of command line tools to search and fetch NGS raw data in a powerful way.

Finally, using different datasets, we will practice screening for quality control, filtering reads for better downstream analysis, mapping reads to reference genome and visualize the output.


This course is intended for life scientists who are already dealing with NGS data or willing to efficiently use publicly available NGS data, and would like to be able to start analysing them.

Learning objectives

At the end of the course participants should be able to:

  • distinguish between the different NGS technologies
  • navigate and retrieve efficiently datasets from the The European Nucleotide Archive (ENA) and the Sequence Read Archive (SRA)
  • perform quality control for better downstream analysis, mapping reads to reference genome and visualizing the output.


Knowledge / competencies:

Participants should have a basic understanding of working with command line tools on Linux or Windows-based operating systems. If you do not feel comfortable with UNIX commands, please take our UNIX fundamentals e-learning module.


Participants should bring their own computers and chargers.

Participants should install "The Integrative Genome Viewer (IGV)" on their respective machines.
