This reproducible R Markdown analysis was created with workflowr (version 1.7.0). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.
Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.
The results in this page were generated with repository version a78ffef. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.
Note that you need to be careful to ensure that all relevant files for
the analysis have been committed to Git prior to generating the results
(you can use wflow_publish
or
wflow_git_commit
). workflowr only checks the R Markdown
file, but you know if there are other scripts or data files that it
depends on. Below is the status of the Git repository when the results
were generated:
Untracked files:
Untracked: .DS_Store
Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.
These are the previous versions of the repository in which changes were
made to the R Markdown (analysis/index.Rmd
) and HTML
(docs/index.html
) files. If you’ve configured a remote Git
repository (see ?wflow_git_remote
), click on the hyperlinks
in the table below to view the files as they were in that past version.

This repository contains code and data resources to accompany our research paper:
Yusha Liu, Peter Carbonetto, Jason Willwerscheid, Scott A. Oakes, Kay F. Macleod, and Matthew Stephens (2023). Dissecting tumor transcriptional heterogeneity from single-cell RNA-seq data by generalized binary covariance decomposition. bioRxiv doi:10.1101/2023.08.15.553436.
We provide the following resources:
A vignette that shows how to use GBCD to dissect tumor transcriptional heterogeneity through analysis of multi-tumor single-cell RNA-seq (scRNA-seq) data. We illustrate this using a head and neck squamous cell carcinoma (HNSCC) dataset analyzed in our research paper.
The scripts that reproduce the results and figures presented in the research paper.
Implementing GBCD requires installing the R packages ashr (version 2.2-54), ebnm (version 1.0-42) and flashier (version 0.2.50), which were previously developed by our lab. All the analyses in this research paper were performed in R (version 4.1.0).

The analysis contains R Markdown source files for the workflowr website, including a vignette illustrating how to apply GBCD to analyze your own scRNA-seq data from malignant cells collected from multiple patients and/or studies.
The code directory contains the R source code to implement GBCD, using the functions defined in the ebnm and flashier packages previously developed by our lab.
The docs directory contains webpages generated from the R Markdown files in the analysis directory.
The hnscc directory stores the preprocessed HNSCC dataset analyzed in our research paper, and the results and analysis scripts of the HNSCC data to reproduce the relevant figures in the research paper.
The pdac directory stores the results and analysis scripts of the pancreatic cancer adenocarcinoma data to reproduce the relevant figures in the research paper.
The simulations directory stores the results and analysis scripts related to the simulation study to reproduce the relevant figures in the research paper.
Please note that running these scripts may give you results that are slightly different from those presented in the paper (which were generated much earlier), particularly the GBCD results, due to version updates of the model fitting algorithm. However, the conclusions reported in the paper remain unaffected.
