        Bracken relies on Bayesian probabilities that derive from the knowledge about the Kraken classification of each read-length kmer from all genomes within the provided Kraken database. It takes the tabular report output of kraken/kraken2 representing abundance of all detected taxa and provides as output a table representing the re-estimated abundances of different taxa at the taxonomy level pre-determined by the user. For more information about the operation behind the scene, visit http://ccb.jhu.edu/software/bracken/index.shtml?t=manual.

        Prior to abundance estimation with bracken, we must divide each genome in the Kraken database into read-length kmers, classify each of those kmers and store as a data structure. This indexing step has already been performed for you and it suffices to select the name of the correct kraken DB that you used for read classification.

        Bracken output file format (tabular):
           * Taxon name
           * Taxonomy ID
           * Level ID (S=Species, G=Genus, O=Order, F=Family, P=Phylum, K=Kingdom)
           * Kraken assigned reads
           * Added reads with abundance re-estimation
           * Total reads after abundance re-estimation
           * Fraction of total reads
