RNA-Seq is a widely used method for analyzing gene expression. This workshop focuses on differential expression analysis using R, guiding participants through essential steps from raw count data to identifying differentially expressed genes.
- Understand the basics of RNA-seq data analysis
- Perform normalization, model fitting, and hypothesis testing
- Identify differentially expressed genes
- Interpret and visualize results
- Basic knowledge of R and RStudio
- install required R packages listed in requirements.R
Welcome, everyone! Today, we'll be diving into RNA-Seq data analysis, specifically looking at differential gene expression analysis using R. RNA sequencing, or RNA-seq, is a powerful technique that allows us to study gene expression at a depth and resolution far beyond what we could achieve before. It has transformed our ability to understand how genes are expressed under various conditions, whether in healthy tissue versus disease, different time points, or across various experimental treatments. Throughout this session, we'll go from raw sequencing counts to identifying differentially expressed genes, covering the essential steps and statistical methods along the way.
The goal of today’s workshop is to equip you with the knowledge to process, analyze, and interpret RNA-seq data. We’ll also cover practical tips and hands-on R code, so by the end, you’ll have both the foundational understanding and some practical tools you can use in your own projects.
