Fig. 4From: Visibiome: an efficient microbiome search engine based on a scalable, distributed architectureVisibiome’s workflow. The figure outlines the typical workflows when using Visibiome. The upper part deals with the Web interface and user interaction. At the core of Visibiome are two analysis types, comprehensive/phylogeny based and quick/non-phylogenetic distance based. Note that Analysis Type I (GNAT search) selectively compares to chosen database samples during GNAT traversal which are specific to the query sample. For some parts of the visualization however, a complete beta diversity distance matrix is required. As a consequence, the algorithm chooses M’ samples from the intersection of the individual search spaces. Moreover, barcharts for compositional comparisons ∗ are currently only generated for Analysis Type IBack to article page
