Three-options mapping analysis. Some data from GMAP-based mapping analysis. a Abundance plot for the averaged Lean (blue) and Obese (orange) metagenomes of the most read-abundance genomes. The plot depicts total mapped reads per specie in the two averaged metagenomes. b Three-option abundance by organism. In blue, total first option abundance, (number of reads assigned). In red and green, the number of times an organism was the second and third best candidate for a read. Bacteria with red or green peaks reveal that another organism is probably hiding them (regarding abundance) and there is not a direct consensus. c Total reads assigned in log10 scale per species as best candidate (first option, blue) and from that total, the number of reads that had two very similar candidates (defined as a distance in terms of identity, length and coverage) from the second best candidate (in red). d An exhaustive-one-vs-all user-defined analysis where a bacterium is compared against all species in the database. The peak in the plot (near the middle) is the analyzed genome, Ruminococcus obeum ATCC 29,174. This particular scenario depicts a comparison of the target genome against all species by length and abundance. In blue, the percentage of reads that were mapped as second candidate when the best candidate was the target genome. In orange, the average length of such mapped reads
