Introduction

On this page you can see the beating heart of sanger-tol - the size of our community and the output of our work.

Click to expand: How these numbers are collected and what caveats should be considered

Please bear in mind the following points when looking over these numbers:

  • Pipelines maybe worked on before they are transferred to sanger-tol. The age, stars and other metrics of the original parent repository are not shown.
  • Metrics are for the default (main) branch only
  • Commits and contributors are only counted if associated with a GitHub account
  • nextflow pull and nextflow run uses git to clone a remote repo the first time it runs, so the clones count gives some idea of usage. However:
    • Unique cloners is based on IP address, so will under-represent institutional users sharing a single external IP address
    • Unique cloners is based on IP address, so will over-represent cloud users using multiple IP addresses
    • Traditional HPC centres may share workflow installations, so only have one clone for many users  /  pipeline runs
    • Cloud users will typically spin up a new instance and clone the workflow every time that they run a pipeline.
  • Clone counts and repositoriy views are only available for two weeks - longer term data collection for sanger-tol repos started in July 2023 This is when we started counting the totals.
  • Metrics are fetched once per day (last checked 2025-06-23).

GitHub organisation members

We use GitHub to manage all of the code written for sanger-tol. It's a fantastic platform and provides a huge number of tools. We have a GitHub organisation called sanger-tol.

It is not required to be a member of the sanger-tol GitHub organisation to contribute. However, members get the sanger-tol logo listed on their profile page and full write-access to all sanger-tol repositories.

By default, organisation membership is private. This is why you'll see a lower number if you visit the sanger-tol organisation page and are not a member.

GitHub contributors

Anybody can fork sanger-tol repositories and open a pull-request. Here we count how many different people have contributed at least one commit to an sanger-tol repository, or created or commented on an issue or pull-request.

Plot truncated to start of 2022 (some pipelines moved to sanger-tol so have older contributions).

Additionally, GitHub tracks how many times people view repository web pages on github.com.

Pull Requests

When people contribute code to a sanger-tol repository, we conduct a "Pull request" - other members of the sanger-tol community review the proposed code and make suggestions, before merging into the main repository.

Pull Request response times

Pull-requests are reviewed by the sanger-tol community - they can contain discussion on the code and can be merged and closed. We aim to be prompt with reviews and merging. Note that some PRs can be a simple type and so very fast to merge, others can be major pipeline updates.

First response is when a comment is made by a GitHub user other than the original PR author

Contributor Leaderboard

We value each and every contribution to sanger-tol, no matter how small. However, that doesn't mean that we can not get competitive!

Here are the latest stats of who has contributed the greatest number of commits.

Remember
  • There is more to contributing than commits! We're not counting issue comments, reviews or anything else here.
  • People merging pull-requests get bonus commit counts from those merge commits.
  • Some people commit often, others not so much. So it's not a perfect representation of amount of work - just a bit of fun!
  • main branch only, and all of the other caveats..
