In this workshop, you will be learning how to analyse RNA-seq count data, using R. This will include reading the data into R, quality control and performing differential expression analysis and gene set testing, with a focus on the DESEq2 analysis workflow. You will learn how to generate common plots for analysis and visualisation of gene expression data, such as boxplots and heatmaps. You will also be learning how alignment and counting of raw RNA-seq data can be performed in R. This workshop is aimed at biologists interested in learning how to perform differential expression analysis of RNA-seq data when reference genomes are available.
Some basic R knowledge is assumed (and is essential). Without it, you will struggle on this course. If you are not familiar with the R statistical programming language we strongly encourage you to work through an introductory R course before attempting these materials. We recommend reading our R crash course before attending, which should take around 2 hours
This course is based on the course RNAseq analysis in R originally prepared by Combine Australia and delivered on May 11/12th 2016 in Carlton. The course was then modified by Cancer Research Uk Cambridge Institute and delivered as part of the CRUK Functional Genomics Autumn School
Who should attend this course?
Researchers in life sciences who want to get an appreciation for the computational steps involved in RNA-seq analysis, and how to execute best-practice RNA-seq workflows in 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
- 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
- Sources of variation in RNA-seq data
- Command-line tools for processing raw sequencing files in fastq format
- Differential expression analysis using DEseq2
- Annotation resources in Bioconductor
- Identifying over-represented gene sets among a list of differentially expressed genes
You will need to bring an internet-enabled laptop to the course and install the latest versions of both R and RStudio before coming to the course
On the first day of the course, we will provide you with a link to access cloud-based computing resources for the command-line sessions. See here for more details.
Install R by downloading and running this .exe file from CRAN. Also, please download and run the RStudio installer for Windows. Note that if you have separate user and admin accounts, you should run the installers as administrator (right-click on .exe file and select “Run as administrator” instead of double-clicking). Otherwise problems may occur later, for example when installing R packages.
You can download the binary files for your distribution from CRAN. Or you can use your package manager (e.g. for Debian/Ubuntu run
sudo apt-get install r-base and for Fedora run
sudo yum install R). Also, please download and run the RStudio installer.
