A taxonomy database consists of unaligned sequences in fasta format and a taxonomy file. The taxonomy file is a two column text file where the first column is the name of the sequence and the second column is a string of taxonomic information separated by semicolons. This information should not include spaces and the last character must be a semi-colon. For example, the first lines of silva.slv.taxonomy are as follows:
U87775.1 Bacteria;Alphaproteobacteria;Rhizobiales;Azorhizobium_et_rel.;Methylobacterium_et_rel.;Bosea; DQ904772.1 Bacteria;Firmicutes;Clostridiales;Ruminococcus_et_rel.;Anaerofilum-Faecalibacterium;Faecalibacterium;Faecalibacterium_prausnitzii; AY553109.1 Bacteria;Firmicutes;Bacillales_Mollicutes;Bacillus_subtilis_et_rel.;Bacillus_carboniphilus_et_rel.;Bacillus_licheniformis-pumilus-subtilis; AY553101.1 Bacteria;Firmicutes;Bacillales_Mollicutes;Bacillus_subtilis_et_rel.;Bacillus_carboniphilus_et_rel.;Bacillus_licheniformis-pumilus-subtilis;
