Relative contributions of higher-level taxa to functional categories were determined using the metagenome_contributions. We used PICRUSt to estimate bacterial gene content; because the input is 16S rRNA gene data, we did not capture any eukaryotic or viral contributions to the metagenome. To explore the skin microbe-host interaction further, we used PICRUSt , an algorithm that detects the functional capabilities of a community by comparing its metagenome with reference genomes using microbial communities identified from all subjects. The first part of this tutorial will use PICRUSt, while the second part will use R for plotting. However, it only works adequately for those environments where the results have large numbers of organisms with annotated reference genomes available. To deeply understand obesity and the metabolic mechanism related to gut microbiota would make an improvement in the treatment of obesity. , read mapping, k-mer alignment, and composition analysis. For each genome-specific taxon t and its abundance (t,ab t) ∈ P out, its genome size s t, together with the total number of reads n in the sample, determines the number of generated reads n t (Eq. PICRUSt was used to predict the genomic repertoire of each community metagenome [47]. 05 in this metagenome analysis. PICRUSt; Langille et al. py command in PICRUSt and the abundances of these bacterial groups were plotted separately for each function in R.
