From: Rapid phylogenetic and functional classification of short genomic fragments with signature peptides
The metagenomic read analysis process. Metagenomic reads are translated in the 6 possible reading frames as peptides and indexed as 10-mers of amino acids. This index is searched for phylogenetic signatures and the node assignments of the signatures are collated per read. Reads are assigned to nodes on the phylogenetic tree at the most specific node for which there is consistent evidence via the greatest common descendant algorithm.
