We are delighted to announce the addition of a new community-developed curriculum on Metagenomics to The Carpentries Lab. The curriculum was peer reviewed in the Lab Reviews repository and approved for inclusion in The Carpentries Lab on 24th February 2023.
The Carpentries Lab was set up as a space for peer-reviewed lessons developed by the community. Designed to complement The Carpentries Incubator, where the community collaborates on the development of new lessons on a wide range of topics, the Lab is intended to serve as a platform for open peer review of these community-developed lessons and the hosting of lessons that have passed through that review process.
About the curriculum
The Metagenomics curriculum is intended to be used by anyone interested in conducting microbiome research with metagenomics analysis. The curriculum starts with basic recommendations on working with bioinformatics and data-based projects, and it teaches from scratch the programming skills required to do these kinds of projects. Here you will learn the language bash with enough depth to navigate the filesystem, edit files from the command line, automate tasks with scripts, and run programs. You will also learn the basics of the R language to analyse data using special libraries and make graphs. These skills will allow you to conduct a complete metagenomics workflow, from sequencing reads to diversity analysis, using a standard pipeline and giving you the tools to explore more of the available programs and build your own workflow.
This curriculum was created by undergrad and graduate students and researchers who were having a hard time knowing where to start on their metagenomics project. They joined forces to put together a comprehensive workflow and decided to share it with the rest of the struggling scientists in the world.
About the review process
The curriculum was reviewed in a public issue thread on The Carpentries Lab
reviews repository. After some initial editorial checks,
the curriculum was reviewed by two volunteers from The Carpentries community: Paula Nieto Garcia and Fotis Psomopoulos.
These reviewers were invited based on their expertise as Carpentries Instructors and their domain knowledge in metagenomics and related fields.
The peer-review process enhanced the lesson by rearranging and breaking down several episodes, making them more connected and reducing the cognitive load. It improved the software setup by making it easier to install in a wider range of settings, and the instructions were simplified in a way that made them easier to maintain. Over all of the episodes, the reviewers helped with the clarity of the contents and the distribution and delivery of the exercises by making them more helpful for practice and a self-evaluation of the contents learned.
The review process allowed the authors to make sure that the lessons were understandable and fluent from a fresh perspective. The reviewers were attentive to detail, corroborated that the code works as intended, and proposed changes that were in line with the author’s intention. The editor’s list of requirements helped them understand what was important to include and put more attention to, such as the accessibility of the pages and figures. The reviewer’s comments were added at each point of the editor’s checklist, which was useful for understanding the context of the comment, but it may be easier to address the comments in a list of issues in the lesson’s repository and mention them in the corresponding point of the checklist. Each issue could have the comment and the proposed change along with a label of the priority of the changes.
The authors intend to use the lesson for formal undergrad courses in bioinformatics and independent workshops. They will also use the experience that this lesson development gave them to create more curricula on new topics and have more ideas to expand the Metagenomics curriculum in the future.
The wider Carpentries community can now find these lessons in The Carpentries Lab, use and adapt them to teach their own workshops, contribute feedback, and suggest improvements:
- Metagenomics Workshop Overview
- Project Organization and Management for Metagenomics
- Introduction to the Command Line for Metagenomics
- Introduction to R
- Data Processing and Visualization for Metagenomics
The Carpentries Lab is looking for reviewers! To volunteer to review a lesson in the Lab, please read our Guide for Reviewers, and register as a reviewer so we can contact you when relevant lessons are ready for review.
Lessons in the Incubator can be submitted for review in the Lab by opening an issue on the
We are very grateful to everyone who helped make this first review in The Carpentries Lab a success. The authors would like to thank Karina Enriquez Guillén and Rafael Pérez Estrada for their valuable contributions while testing the lessons.
Congratulations to the authors for creating an excellent curriculum that will prove a useful resource to so many people:
