EggNOG-mapper (a.k.a. emapper.py or just emapper) is a tool for fast functional annotation of novel sequences. It uses precomputed orthologous groups (OGs) and phylogenies from the eggNOG database (http://eggnogdb.embl.de/) to transfer functional information from fine-grained orthologs only.

Common uses of eggNOG-mapper include the annotation of novel genomes, transcriptomes or even metagenomic gene catalogs.
