+**PICRUSt: Phylogenetic Investigation of Communities by Reconstruction of Unobserved States**
+
+The PICRUSt project aims to support prediction of the unobserved character states in a community of
+organisms from phylogenetic information about the organisms in that community. The primary application
+is to predict gene family abundance (e.g. the metagenome) in environmental DNA samples for which only
+marker gene (e.g. 16S rRNA gene) data are available. This is an open source, international, collaborative
+bioinformatics project developed in the Huttenhower, Beiko, Langille, Vega Thurber, Knight and Caporaso labs.
