MOSAIC Community Challenge: Strains
Accelerate development of computational methods that can unravel the microbiome at finer resolution
You should participate if you are a:
- benchmark your method without spending your time installing others’ methods
- focus your time improving your method
- share your method with the entire community (only if you want to!)
Microbiome Scientist in Academia
- find and test methods most suitable for your dataset
- access to community-validated methods
- guarantee reproducibility
Microbiome Scientist in Industry
- test and integrate community validated methods (appropriate license applicable) into your own pipelines
- enable frictionless portability into secure and GXP-compliant environment for clinical research
- collaborate by sharing data and pipelines between teams
- Create Mosaic account and receive $50 worth of compute credits if you do not have a DNAnexus account yet!
- Read through the Rules of Participation and accept the Challenge.
Work on the Challenge by either:
Learn more about submitting your results.
- Creating your app on Mosaic, run it FOR FREE and submit results in the required format (and if you choose to share your method), or,
- Downloading the datasets, working outside Mosaic and submitting the results in the required format
Methods will be evaluated with the following metrics:
- Profiling: Precision, Recall and F1-score
- Assembly: Genome fraction, misassemblies and indels+mismatches (per 100kb)
- Binning: Precision, Recall and Adjusted Rand Index
These metrics are by no means exhaustive, rather are meant to create community discussion around appropriate metrics for evaluating different types of methods.
See Evaluation metrics for details.

The microbiome industry is gearing up to introduce microbial-based products. Profiling a microbiome sample is the fundamental step in any microbiome analysis, but becomes even more challenging when higher resolution really matters. Current state-of-the-art methods based on next-generation sequencing are able to predict organisms down to the genera and species level. However, within the same species, individual strains can elicit different functionality and metabolic response, making strain-level identification and quantification key to the development and tracking of microbiome-based health solutions. It is critical to be able to accurately determine the type and quantity of microbes in a sample at the strain level in order to bring safe and effective products to market, and to accurately monitor their status within the human body. Participants will contribute to the improvement of sequencing standards while also testing their own tools and methods in a secure and collaborative environment.
