More details on the workshop are below.
For the ISCB 2022 workshop, an RStudio in the cloud will be provided with everything installed, all that participants will need is a web browser.
If you want to install the packages and material post-workshop, the instructions are below. The workshop is designed for R 4.1 and can be installed using one of the two ways below.
If you're familiar with Docker, you could use the Docker image which has all the software pre-configured to the correct versions.
docker run -e PASSWORD=abc -p 8787:8787 ghcr.io/tidytranscriptomics-workshops/iscb2022_tidytranscriptomics
Once running, navigate to http://localhost:8787/ and then login with
Username:rstudio and Password:abc.
You should see the Rmarkdown file with all the workshop code which you can run.
Alternatively, you could install the workshop using the commands below in R 4.1.
#install.packages('remotes')
# Need to set this to prevent installation erroring due to even tiny warnings, similar to here: https://github.com/r-lib/remotes/issues/403#issuecomment-748181946
Sys.setenv("R_REMOTES_NO_ERRORS_FROM_WARNINGS" = "true")
# Install same versions used in the workshop
remotes::install_github(c("stemangiola/tidyseurat@v0.5.1", "stemangiola/tidySingleCellExperiment@v1.3.2"))
# Install workshop package
remotes::install_github("tidytranscriptomics-workshops/iscb2022_tidytranscriptomics", build_vignettes = TRUE)
# To view vignettes
library(iscb2022tidytranscriptomics)
browseVignettes("iscb2022tidytranscriptomics")
To run the code, you could then copy and paste the code from the workshop vignette or R markdown file into a new R Markdown file on your computer.
This tutorial will present how to perform analysis of single-cell RNA sequencing data following the tidy data paradigm. The tidy data paradigm provides a standard way to organise data values within a dataset, where each variable is a column, each observation is a row, and data is manipulated using an easy-to-understand vocabulary. Most importantly, the data structure remains consistent across manipulation and analysis functions.
This can be achieved with the integration of packages present in the R CRAN and Bioconductor ecosystem, including tidyseurat, tidySingleCellExperiment and tidyverse. These packages are part of the tidytranscriptomics suite that introduces a tidy approach to RNA sequencing data representation and analysis. For more information see the tidy transcriptomics blog.
- Basic familiarity with single-cell transcriptomic analyses
- Basic familiarity with tidyverse
The workshop format is a 2 hour session consisting of lecture, hands-on demo, exercises and Q&A.

- Compare Seurat and SingleCellExperiment and tidy representation
- Apply tidy functions to Seurat and SingleCellExperiment objects
- Reproduce a real-world case study that showcases the power of tidy single-cell methods
- Basic tidy operations possible with tidyseurat and tidySingleCellExperiment
- The differences between Seurat and SingleCellExperiment representation, and tidy representation
- How to interface Seurat and SingleCellExperiment with tidy manipulation and visualisation
