We are using a subset of the data here so that the analyses can be run quickly, without a large amount of computing power.

This contains 50,000 paired 16S amplicon reads, which is a subset of the full SRR7140083 dataset. This tool uses the RDP classifier to output an interactive graph of microbial diversity.Д¬lick on the file SRR7140083_50000. The final exercise in the tutorial uses the 16S Biodiversity tool to classify the processed amplicon reads.

You will need to install these from the Plugins menu in Geneious if you have not already done so.ДЄlthough this tutorial focusses on 16S, this pipeline can be applied to any other metagenomic marker, such as 18S, ITS, CO1, provided a suitably curated database for BLAST searching is available. In the final step the BLAST results are used as a targeted database for classifying the read set with the Sequence Classifier plugin.ДЇor this tutorial you will need the BBDuk and Sequence Classifier plugins. Representative sequences are then BLASTed to the preformatted 16S Microbial database from NCBI, which is a curated set of 16S sequences from bacteria and archaea type strains. The approach outlined in this tutorial firstly trims, filters and clusters sequences into OTUs using the de novo assembler. The key to obtaining a reliable classification of your amplicon data is to use a suitably curated database of reference sequences. See SRR7140083 for the original Short read Archive (SRA) submission.

The sequence was generated using an Illumina MiSeq, with 2 x 250 bp read lengths. This dataset comprises paired-read data from a 16S rRNA amplicon spanning about 260bp of subunit V4. In this example we will analyse 16S rRNA sequences PCR-amplified from naturally fermented sauerkraut, in order to profile the bacterial community associated with the fermentation process. Metagenomics is the study of genetic material recovered directly from environmental samples. This tutorial describes a strategy for assembling, filtering and analyzing a metagenomic data set in Geneious.
