Introduction to RNA-seq data analysis

Updated

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.

The training room is located on the first floor and there is currently no wheelchair or level access available to this level.

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

During this course you will learn about:

• RNA sequencing technology and considerations on experiment design

• 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
