Aggregate Summary Page

The 16S Metagenomics App provides a comparison of all samples on the Aggregate Summary page. You can view interactive charts showing comparisons of sample results, or download aggregate result files.

Aggregate Results

The aggregate results section contains summary files for download. The PDF Aggregate Summary Report contains tables showing the same information as in the BaseSpace report. The CSV files contain the number of reads classified to each classification by sample, organized by taxonomic level of the classifications.

Sample Information

The Sample Information table provides the Sample Number, Sample ID, and statistics about genus-level classification rate and primary analysis for each sample.

Principal Coordinate Analysis (PCoA)

Principal coordinate analysis shows similarity between normalized relative abundance of all samples. The PCoA is generated using Classical MDS on a Pearson covariance distance matrix generated from per-sample normalized classification abundance vectors. You can select the maximum level at which to compare samples by adjusting the scrollbar above the chart. Points are labeled with a shortened version of the Sample ID, you can mouse over any point to view the full Sample ID.

Hierarchical Clustering Dendrogram

The dendrogram shows a hierarchical clustering of samples based on genus-level classifications. Mouse over the bar charts to view taxonomic labels.
