Additional file 12 of Metagenomic insights into the microbial communities of inert and oligotrophic outdoor pier surfaces of a coastal city

Additional file 12: Figure S8. Relative abundance of COG categories in the MAGs differed by phylum. The distribution of the data and its probability density are indicated by a violin plot, and the interquartile range of the data is shown by a standard boxplot. Differences between phyla were statistically significant (KW test, p < 0.05) for all COG categories except [Z]. The statistical p-value for each individual COG comparison is provided in Table S4. For Acidobacteria, Firmicutes, and Gemmatimonadetes (each with a single MAG), the relative abundance in each COG category is indicated by a gray point. The absence of any symbol represents a COG category that is not found in a phylum.
