eggNOG-mapper is a tool for fast functional annotation of novel sequences. It uses precomputed orthologous groups and phylogenies from the eggNOG database to transfer functional information from fine-grained orthologs only.

Environment Modules

Run module spider eggnog-mapper to find out what environment modules are available for this application.

System Variables

  • HPC_EGGNOG-MAPPER_DIR - installation directory
  • HPC_EGGNOG-MAPPER_BIN - executable directory
  • EGGNOG_DATA_DIR - application databases directory


If you publish research that uses eggnog-mapper you have to cite it as follows:

Please cite the following two papers if you use eggNOG-mapper v2:
