Phylogeneticist with Experience in ESS Projects? You’re in Luck...

Jonathan Eisen is reaching out on his blog, calling for help on phylogenetic analyses of metagenomic data. He’d like to perform a variety of phylogenetic analyses of data from environmental shotgun sequencing projects and hopes to get lots of different people involved. He writes: “We would like to take sequence reads that contain matches to specific gene/gene family (e.g., RecA, my favorite gene), build a multiple sequence alignment that includes these reads as well as all members of this gene family from known organisms, and then build phylogenetic trees from these alignments.” Go to his blog, The Tree of Life, to make suggestions, ask questions, and get involved.
