Overview

The aim of this course is to familiarise the participants with long read (also called “third generation”) sequencing technologies, their applications and the bioinformatics tools used to assemble this kind of data. Multiple sequencing platforms, including Pacific Biosciences and Oxford Nanopore MinION, are now available to generate reads that are several kilobases-long. It is also possible to assemble Illumina reads to generate in-silico long reads. These improvements have greatly facilitated the assembly of genomes but some other applications are emerging, for example, for haplotype phasing, or for the study of alternative splicing using RNA-seq.

This course will be composed of an introduction to the techniques and data analysis methods, a minisymposium and a hands-on session. The minisymposium will consist of short presentations by SIB researchers on the applications of these technologies. It will be followed by a panel discussion between speakers and the audience, letting the opportunity to debate on the advantages and pitfalls of these technologies for research projects. The hands-on session will consist of computer exercises that will enable the participants to familiarize with real datasets from different technologies and the bioinformatics tools to assemble genomes.

Audience

This course is aimed at PhD students, post-doctoral and researchers in life sciences who would like to have a grasp of these technologies or who are planning to use and analyze them in their research.

Learning objectives

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

  • Identify the various applications, advantages and limitations of the methods presented
  • Assess the quality of your datasets
  • Extract raw reads and align them to a reference genome
  • Use the reads to assemble genomes de novo

Prerequisites

Knowledge / competencies:

Participants should have a good understanding of 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.

We also recommend a basic knowledge of the file formats used in the short reads NGS techniques (fastq, SAM/BAM, annotation file formats).

Technical:

Participants should bring a laptop with at least 4 GB RAM, 50 GB free disk space, and WIFI preinstalled.

Additional information

The morning session will feature presentations from the following speakers (see the program below): Christian Ahrens, Laurent Falquet, Mark Robinson, Julien Roux, Ioannis Xenarios. The afternoon session will be taught by Julien Roux and Kamil Jaron (Evolutionary Bioinformatics Group, UniL and SIB) and Walid Gharib (Interfaculty Bioinformatics Unit, UniBe and SIB).

Coordination: Patricia Palagi (SIB Training Group), Julien Roux (Evolutionary Bioinformatics Group, UniL and SIB) and Walid Gharib (Interfaculty Bioinformatics Unit, UniBe and SIB).

We will recommend 0.25 ECTS credits for this course (given the full day is attended, and a passed exam at the end of the session). 

You are welcome to register to the SIB courses mailing-list to be informed of all future courses and workshops, as well as all important deadlines using the form here.
