Long reads applied to plant genome assembling

This course is co-organised by the CUSO/StarOmics doctoral program. Priority is given to its members, but is open to everyone.

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. This will be demonstrated on a non-model organism such as oak genome that has been studied at the University of Lausanne (www.napoleome.ch). Participants will assemble a plant genome during hands-on sessions, which will serve as an exemplar how to tackle genome assembly and all the assessment that are necessary in today's research.

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 researchers on the applications of these technologies and algorithm behind fast and accurate assembly. The mini symposium will host a scientist from the NHGRI (Sergey Koren), Emmanuel Schmid (Vital-IT/SIB), Robert Waterhouse (DEE/UNIL/SIB), Damien Lieberherr (Swss-Prot/SIB). The speakers will cover topics from genome assembly to evaluation of annotation and gene correction.

Audience

This course is addressed in priority to PhD students and postodcs.

Learning objectives

At the end of the course, the participants are expected to have learned what is the current state of the art technology and approaches and caveat in genome assembly assessment.
