Description
This lecture covers the process from count matrix to statistical analysis results (differential expression). More specifically, it covers experimental design, normalization, statistical modeling and parameter estimation, multiple hypothesis testing and a more detailed look at some of the most common differential expression methods as well as a comparison between them.
Aims
The aim of the lecture is to introduce the audience to differential expression analysis of RNA-seq data, to point to pitfalls and best practices, and to show how to apply the most commonly used methods.
Prerequisites
- Know what a count matrix represents
- Some basic background in statistical hypothesis testing
Target audience
beginner, biologist
Learning objectives
- Recognizing the need for normalization
- Choosing an appropriate strategy for differential expression analysis
- Performing differential expression analysis
- Interpreting the output
Materials
- Lecture slides
Data
- The Bottomly data set (downloaded from ReCount) is used to create some of the slides.
Timing
Approximately half a day of lecture
Content stability
The content is relatively stable. Some parts may need to be updated if significant new differential expression methods come along.
