Résumé
RAPPAS: Rapid Alignment-free Phylogenetic Placement via Ancestral SequencesRAPPAS is a program dedicated to "Phylogenetic Placement" (PP) of metagenomic or metabarcoding reads on a reference tree. As apposed to previous PP programs, RAPPAS is based on the phylo-kmers idea, detailed in tis manuscript and uses a 2 step approach divided into a) the database build, and b) the placement itself.This README contains short instructions to build and launch RAPPAS.You will find more detailed instructions, test datasets, pre-built databases and tutorials and discussions related to phylogenetic placement on the wiki page (https://github.com/phylo42/RAPPAS/wiki).
