Table 2. Summary of metagenomes by type and biome used in this study.
Biome | Number of viral metagenomes | Number of microbial metagenomes |
Aquatic | 1 | 58 |
Terrestrial | 9 | 6 |
Host-associated (total) | 65 | 63 |
Host-associated (human) | 62 | 50 |
Total | 75 | 127 |
The metagenomes were previously published and available through NCBI. The metagenomes were not targeted to a single loci and the mean read length was above 150 bp after trimming and filtering.
