In contrast to the Bulk RNA sequencing used to quantify the abundance of gene and transcript expression at a whole population level, single-cell RNA sequencing (scRNAseq) allows researchers to study gene expression profile at a single cell resolution while enabling the discovery of tissue specific sub populations and markers. For example, contrasting different sample conditions i.e. disease vs. normal using scRNAseq can help identify sub-cellular differential behaviours and thus target specific gene markers. This 2-days course will cover the main technologies as well main aspects to consider while designing a scRNAseq experiment including a hands-on practical data analysis session applied to droplet-based methods.


First day

Introduction to scRNAseq:

  • Technologies
  • Experimental design

Quality control

  • Dropouts - Doublets
  • Ribosomal / mitcochondrial RNAs

Normalization and scalability

  • Feature selection
  • Log scaling
  • confounding factors removal

Second day

Dimentionality reduction and cell type clustering

  • PCA
  • tSNE
  • UMAP
  • Clustering methods (Hierarchical, K-means and Graph-based)

Differential expression analysis

  • Methods overview
  • DE between clusters
  • DE between samples (involving data-integration)

Cell type identification

  • Methods and applications

Pseudotime analysis

  • Methods and applications


This course is intended for life scientists and bioinformaticians familiar with "Next Generation Sequencing" who wish to acquire the necessary skills to analyse scRNA-seq gene expression data.

Learning objectives

At the end of the course attendees will be able to:

  • distinguish advantages and pitfalls of scRNAseq
  • design their own scRNA-seq experiment
  • apply a downstream analysis using UNIX and R

Knowledge / competencies prerequired (Mandatory)

Participants should already have a basic knowledge in Next Generation Sequencing (NGS) techniques, or have already followed the "NGS - Quality control, Alignment, Visualisation" given twice a year at the SIB. Knowledge in RNA sequencing is a plus. A basic knowledge of the R statistical software and completion of an introductory course on UNIX (eg UNIX fundamentals) or equivalent knowledge is also required.

Technical requirements

A Wi-Fi enabled laptop.
