Building a global metagenomics portal ('MGportal') to handle next-generation sequencing data and associated metadata

While genomes represent the full genetic (DNA) complement of a single organism, metagenomes represent the DNA of an entire community of organisms. These organisms might be free-living in the environment, or be found on the skin or in the gut of a human being or other species. Microbial organisms play a major role in our everyday health and well-being, which is not surprising when you consider that the number of microbial cells in or on an average human body actually exceeds the number of human cells! Microbes play a similarly important role in the environment; different types of organisms live under different conditions (including extreme habitats, such as the run-off from acid mines or the depths of the oceans). Understanding how these organisms have adapted to their various living conditions will lead to a better understanding of how changes in the environment will have impact on biodiversity in the future. It may also lead to discovery of entirely new species or novel proteins which could have utility as antibiotics or other drugs. Combined with other types of 'omic data, metagenomes hold the promise of unparalleled insights into fundamental questions across a range of fields including evolution, ecology, environment biology, health and medicine. To fully exploit the promise of these data we need both scientific innovation and community agreement on how to provide appropriate stewardship of these resources for the benefit of all. Significant numbers of metagenomics projects have been awarded grants by international funding bodies. Whilst all of these projects have specific, scientifically-interesting aims, they mostly exist in isolation, with little or no cross-referencing to other metagenomic or genomic datasets. Our intention is to leverage existing infrastructure to deliver a world-class metagenomics resource with unique utility for UK-based metagenomics researchers. This resource, MGportal, will utilise user-friendly interfaces, state-of-the-art algorithms and the EBI's unique position as a hub of biological information to measurably enhance the value of these researchers' data. It will be built in close collaboration with the Genomic Standards Consortium (GSC). MGportal will consist of software tools to enable metagenomics researchers to upload their data to the raw nucleotide sequence archives, data analysis pipelines to predict what potential genes are present in the data and what their function is, plus a web interface which will display these data and results in a way that is easy to browse and query. We will hold training courses and a workshop to gain input from the scientific community about the portal. It is hoped that MGportal will eventually allow researchers to understand the results of their metagenomics experiments, as well as seeing how those results compare with the outcomes of other studies.
