Single-cell RNA-seq data analysis workshop

Audience Computational skills required Duration
Biologists Introduction to R 3-session online workshop (~7.5 hours of trainer-led time)

Description

This repository has teaching materials for a hands-on Introduction to single-cell RNA-seq analysis workshop. This workshop will instruct participants on how to design a single-cell RNA-seq experiment, and how to efficiently manage and analyze the data starting from count matrices. This will be a hands-on workshop in which we will focus on using the Seurat package using R/RStudio. Working knowledge of R is required or completion of the Introduction to R workshop.

Note for Trainers: Please note that the schedule linked below assumes that learners will spend between 3-4 hours on reading through, and completing exercises from selected lessons between classes. The online component of the workshop focuses on more exercises and discussion/Q & A.

These materials were developed for a trainer-led workshop, but are also amenable to self-guided learning.

Learning Objectives

  • Explain common considerations when designing a single-cell RNA-seq experiment
  • Discuss the steps involved in taking raw single-cell RNA-sequencing data and generating a count (gene expression) matrix
  • Compute and assess QC metrics at every step in the workflow
  • Cluster cells based on expression data and derive the identity of the different cell types present
  • Perform integration of different sample conditions

Installation Requirements

Applications

Download the most recent versions of R and RStudio for your laptop:

Packages for R

Note 1: Install the packages in the order listed below.

Note 2:  All the package names listed below are case sensitive!

Note 3: At any point (especially if you’ve used R/Bioconductor in the past), in the console R may ask you if you want to update any old packages by asking Update all/some/none? [a/s/n]:. If you see this, type "a" at the prompt and hit Enter to update any old packages. Updating packages can sometimes take quite a bit of time to run, so please account for that before you start with these installations.

Note 4: If you see a message in your console along the lines of “binary version available but the source version is later”, followed by a question, “Do you want to install from sources the package which needs compilation? y/n”, type n for no, and hit enter.

(1) Install the 4 packages listed below from Bioconductor using the the BiocManager::install() function.

  1. AnnotationHub
  2. ensembldb
  3. multtest
  4. glmGamPoi

Please install them one-by-one as follows:

BiocManager::install("AnnotationHub")
BiocManager::install("ensembldb")
& so on ...

(2) Install the 8 packages listed below from CRAN using the install.packages() function.

  1. tidyverse
  2. Matrix
  3. RCurl
  4. scales
  5. cowplot
  6. BiocManager
  7. Seurat
  8. metap

Please install them one-by-one as follows:

install.packages("tidyverse")
install.packages("Matrix")
install.packages("RCurl")
& so on ...

(3) Finally, please check that all the packages were installed successfully by loading them one at a time using the library() function.

library(Seurat)
library(tidyverse)
library(Matrix)
library(RCurl)
library(scales)
library(cowplot)
library(metap)
library(AnnotationHub)
library(ensembldb)
library(multtest)
library(glmGamPoi)

(4) Once all packages have been loaded, run sessionInfo().
