FIG 1.

A visual representation of the whole metagenomic assembly reveals the clustering of contigs with respect to taxonomic classification (a), ¹³C enrichment designation (b), and genome GC content (c). Contigs (>3.5 kb) were clustered by pentanucleotide frequency using the t-SNE multidimension reduction algorithm. This figure reveals the correspondence between taxonomic classification and ¹³C enrichment status (a versus b) and that enrichment status was not correlated with GC content (b versus c). An interactive html version in the supplementary data package at https://osf.io/tb3n4/ allows for detailed exploration of taxonomic annotations for all contigs.
