RNA-seq: From quality control to pathway analysis

This course is oversubscribed.

Overview

This course will present all the bioinformatics tools required to analyze RNA-seq gene expression data, from the raw data to the biological interpretation. This two-day course will discuss the following topics:

• Quality control and reads cleanup
• RNAseq reads mapping to genome & transcriptome
• Gene reads counting, gene & exons differential expression
• GO enrichment and pathway analysis

Audience

This course is intended for life scientists or bioinformaticians with basic knowledge in Next Generation Sequencing and willing to acquire the necessary skills to analyse RNA-seq gene expression data.

Learning objectives

At the end of the course attendees will:

• Understand advantages and pitfalls for RNA sequencing
• Be able to design their own experiment
• Practise the downstream analysis using command line software (QC, mapping, counting, Diff Expression, gene enrichment, pathway analysis)

Prerequisites

Knowledge / competencies: Participants should already have a basic knowledge in Next Generation Sequencing (NGS) techniques or already followed the Introduction to NGS course; A basic knowledge of Unix and the R statistical software is also required.

Technical: Participants should bring their laptop (mininum 4GB RAM and 30 GB of free hard disk space).

Location

University of Bern main building, Hochschulstrasse 4, room 331.
