The detection of genetic variation is of major interest in various disciplines spanning from ecology and evolution research to inherited disease discovery and precision oncology. Next generation sequencing (NGS) methods are very powerful for the detection of genomic variants. Thanks to its throughput and cost-efficiency it enables the detection of a large number of variants in a large number of samples. In this two-day course we will cover the steps from read alignment to variant calling and annotation. We will mainly focus on the detection of germline mutations by following the GATK best practices.


This course is intended for life scientists who are already familiar with general concepts of NGS technologies.

Learning objectives

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

  • Understand important aspects of NGS and read alignment for variant analysis
  • Perform a read alignment ready for variant analysis
  • Perform variant calling according to GATK best practices
  • Perform a variant annotation


Knowledge / competencies:

Participants should have knowledge in NGS techniques, quality control and alignment to a reference genome. Participants should have a basic understanding of working with command line tools on Unix-based systems. You can test your skills with Unix with the quiz here. 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 (and adapters when coming from abroad).


The registration fees are 120 CHF for academics and 600 CHF for companies.

Deadline for registration and free-of-charge cancellation is set to 17/03/2021. Cancellation after this date will not be reimbursed. Please note that participation to SIB courses is subject to this and other general conditions, available here.

You will be informed by email of your registration confirmation.
