# barrnap(1)

rapid ribosomal RNA prediction

## NAME

barrnap - rapid ribosomal RNA prediction

## SYNOPSIS

barrnap \[options\] \<chromosomes.fasta\>

## DESCRIPTION

Barrnap predicts the location of ribosomal RNA genes in genomes. It supports bacteria (5S,23S,16S), archaea (5S,5.8S,23S,16S), mitochondria (12S,16S) and eukaryotes (5S,5.8S,28S,18S).
