The three human microbial sequencing read sets—Illumina GA reads generated from 124 individuals in this study (black; n = 124), Roche/454 reads from 18 human twins and their mothers (grey; n = 18) and Sanger reads from 13 Japanese individuals (white; n = 13)—were aligned to each of the reference sequence sets. Mean values ± s.e.m. are plotted.
