Examples of visualizations by MALINA. Metagenomic samples are denoted by text tags. (A) BCA plot of phylogenetic abundance, with the clusters visualized as ellipses and the samples connected with the centers of their respective clusters by lines. (B) PCA of COGs associated with vitamin metabolism, with drivers shown by red arrows. (C) Dendrogram heatmap of phylogenetic abundance based on hierarchical clustering algorithm (with samples as columns and genera as rows).
