Species Composition displays the species composition of each sample group at different time points after SCI. Through this feature, SCIGAMA displays the classification of microbial communities after SCI. On the home page navigation bar, when the mouse hovers over “Microbiome,” SCIGAMA displays a submenu. After clicking on “Species Composition,” SCIGAMA jumps to a new page that provides the corresponding information.

Species Composition supports display at different taxonomic levels, including seven levels: kingdom, phylum, class, order, family, genus, and species.

The results of Species Composition are presented in a stacked bar chart. The stacked bar chart shows the relative abundance changes at different time points and different sites after SCI. Taking the genus level as an example, each bar represents the relative abundance of a certain species in each group of samples, and different colors represent different categories of microorganisms.
