+rapid, accurate and sensitive labeling of reads and quantification of species
+on desktop computers.  The system uses an indexing scheme based on the
+@dfn{Burrows-Wheeler transform} (BWT) and the @dfn{Ferragina-Manzini} (FM)
+index, optimized specifically for the metagenomic classification problem.
+Centrifuge requires a relatively small index (4.7 GB for all complete
+bacterial and viral genomes plus the human genome) and classifies sequences at
+very high speed, allowing it to process the millions of reads from a typical
+high-throughput DNA sequencing run within a few minutes.")
