Introduction to RNA-seq data analysis
Updated

Mon 3 Sep - Wed 5 Sep 2018

Description

The aim of this course is to familiarize the participants with the primary analysis of RNA-seq data.

This course starts with a brief introduction to RNA-seq and discusses quality control issues. Next, we will present the alignment step, quantification of expression and differential expression analysis. For downstream analysis we will focus on tools available through the Bioconductor project for manipulating and analysing bulk RNA-seq.

Please note that if you are not eligible for a University of Cambridge Raven account you will need to book or register your interest by linking here.

Target audience
  • Graduate students, Postdocs and Staff members from the University of Cambridge, Affiliated Institutions and other external Institutions or individuals
  • Please be aware that these courses are only free for University of Cambridge students. All other participants will be charged a registration fee in some form. Registration fees and further details regarding the charging policy are available here.
  • Further details regarding eligibility criteria are available here
Prerequisites
  • Basic experience of command line UNIX
  • Sufficient UNIX experience might be obtained from one of the many UNIX tutorials available online.
  • Basic knowledge of the R syntax
  • For a real beginner's introduction into R see here. More advanced R instructions can be found at Quick-R or An Introduction to R

Objectives

After this course you should be able to:

  • Design properly your RNA-Seq experiments considering advantages and limitations of RNA-seq assays
  • Assess the quality of your datasets
  • Perform alignment and quantification of expression through different tools and pipelines
  • Know what tools are available in Bioconductor for RNA-seq data analysis and understand the basic object-types that are utilised
  • Produce a list of differentially expressed genes from an RNA-seq experiment
Aims

During this course you will learn about:

  • RNA sequencing technology and considerations on experiment design
  • Quality control of raw sequencing reads: FASTQC and fastx toolkit
  • Read alignment to a reference genome: Hisat2
  • Extract information from SAM/BAM files: samtools
  • Transcriptome reconstruction: stringtie
  • Transcriptome merging, comparison and quantification: gffcompare and stringtie
  • Genome alignment and read count quantification: STAR
  • Lightweight alignment and quantification: Salmon
  • Sources of variation in RNA-seq data
  • Differential expression analysis using edgeR and DEseq
  • Annotation resources in Bioconductor
  • Identifying over-represented gene sets among a list of differentially expressed genes
