[…] () and simpson () indices, and the beta diversity among the samples was measured using weighted unifrac () metric. taxonomic composition, and diversity results were visualized using the r package phyloseq v.1.14.0 (). blastn (basic local alignment search tool) searches against the ncbi (national center for biotechnology information) database of nucleotides (nt) and against the refseq database […]

[…] method. finally, otu tables were produced in a standard biom format for subsequent analyses., all statistical analyses were done using r version 3.3.1 ([], http://www.r-project.org). we used the phyloseq r package for community composition analysis [] to infer alpha diversity metrics at the otu level, as well as beta diversity (between sample distance) from the otu table. community […]

[…] sequences data [] and how erroneous sequences can be detected. due to these challenges, sophisticated pipelines for taxonomic assignment have been developed, like for example qiime [], mothur [], phyloseq [], micca [] and ng-tax [], the latter of which has been developed in our laboratories and provides computationally efficient and accurate taxonomic assignments and quantification of otus […]

[…] can be projected a posteriori, and their significance can be tested post hoc., several of these statistical tools are standardly embedded in sequence analysis pipelines like mothur [], qiime [] or phyloseq [] and allow to capture measures of alpha- and beta-diversity. choices can be made between default analysis routines and more customized procedures where users can adjust specific settings., […]

[…] plasma glucose level) and 122 postpartum samples (79 and 43 from normoglycaemic and diabetic women, respectively)., alpha diversity metrics (richness and shannon’s index) were calculated using the phyloseq r package based on rarefied otu counts. pielou’s evenness index was calculated as shannon’s index/ln (richness). the cross-sectional difference in alpha diversity between groups […]

[…] using the usearch v9.2.64 package. for otu clustering a threshold of 97% similarity was used through the uparse-otu algorithm. α- and β-diversity analyses were calculated using the r package phyloseq v.1.19.1[] and vegan 2.4_2 packets, using the otu table normalized to the smallest sample size. taxa with differential abundance between groups were identified using the kruskal-wallis test […]

[…] all graphs were constructed in r using ggplot2., for downstream analysis of the community composition the otu table and taxonomy files generated by mothur, were imported into r and analyzed using phyloseq (mcmurdie and holmes )., the oligotrophic sites were more acidic compared to the mesotrophic sites and contained less dissolved ch4 (see additional file : figure s1). concentrations of nh4+, […]

[…] reads due to tag-switching as described in ) as a true part of the negative control., diversity estimates (richness and shannon index) were determined using the “estimate_richness” function in phyloseq version 1.16.2 () with r version 3.3.0. significance of the difference in richness between different seasons and location pairs using the wilcoxon rank sum test implemented […]
