The EBI Metagenomics service is an automated pipeline for the analysis and archiving of metagenomic data that aims to provide insights into the phylogenetic diversity as well as the functional and metabolic potential of a sample. You can freely browse all the public data in the repository.
MLTreeMap is a tool that employs full maximum likelihood to give insights into phylogenetic and functional properties of metagenomes and the underlying microbial communities. It does so by detecting and phylotyping a series of relevant marker genes on the submitted DNA fragments. Among these genes are protein coding phylogenetic markers, SSU rRNA genes and markers for important functional pathways. MLTreeMap is available as a web-server and as a stand-alone version.
