The table presents number of reads assigned at the phylum level in MEGAN. For the phylum Proteobacteria, subsets of reads assigned proteobacterial classes are shown. All percentages are given as the percentage of total reads for each filtered metagenome. (Only phyla with at least 1% of the total unique reads in one or both samples are included.)
