This reproducible R Markdown analysis was created with workflowr (version 1.7.2). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.

R Markdown file: up-to-date

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.

Environment: empty

Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.

Seed: set.seed(20251002)

The command set.seed(20251002) was run prior to running the code in the R Markdown file. Setting a seed ensures that any results that rely on randomness, e.g. subsampling or permutations, are reproducible.

Session information: recorded

Great job! Recording the operating system, R version, and package versions is critical for reproducibility.

Cache: none

Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.

File paths: relative

Great job! Using relative paths to the files within your workflowr project makes it easier to run your code on other machines.

Repository version: 686b00f

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 686b00f. 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: 


Ignored files:
    Ignored:    .DS_Store
    Ignored:    data/.DS_Store
    Ignored:    data/imc/
    Ignored:    data/visium/

Unstaged changes:
    Modified:   analysis/visium_02.Rmd

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/public_data.Rmd) and HTML (docs/public_data.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.

Introduction

In this tutorial we will explore some resources for finding publicly available spatial transcriptomics and imaging mass cytometry datasets. Generally, it is much harder to find public IMC datasets compared to spatial transcriptomics datasets. Regardless, we will cover some useful resources for both data types.

For both spatial technologies, it is important to check the “Data availability” section of relevant manuscripts. They often contain links to where the data is stored, typically to public repositories like GEO, Zenodo, or Figshare.

Spatial Transcriptomics Data

10x has a comprehensive list of publicly available data they made available on their website. These data were generated in-house and encompasses a variety of tissues and technologies. Link to website: https://www.10xgenomics.com/datasets.

You can also search GEO. It is a public repository used for storing genomics data. You will get data from different omics technologies (RNAseq, DNA, etc.).

IMC data

Public data is not easy to get hold of.

Cytoforum: https://cytoforum.stanford.edu/viewforum.php?f=10 List all publications that used IMC or Cytof. Maintained by Mike Leiopold from Stanford. Not all papers have made their data publicly available.
