Bioinformatics Processing of 16S Datasets
摘要
This chapter covers methods and best practices for analyzing 16S datasets, with a particular emphasis on the quality control steps, from the preprocessing of the raw sequencing reads to the removal of chimeric amplification products. It describes outputs from the analysis of raw reads that provide the foundation for downstream analyses and interpretation of the microbial community composition and diversity. It provides details of the tools to perform each step and how the framework Qiime2 and a Nextflow pipeline (nf-core/ampliseq) can improve the reproducibility and traceability of the analysis. Finally, it describes Lotus2, an efficient end-to-end pipeline developed at QIB, which allows the user to select the strategy to adopt for feature identification and taxonomic profiling.
