from raw metagenomic reads to ecosystem analytical capability
The ultimate goal of metagenomics is to provide a descriptive and eventually predictive metabolic and taxonomic model of an ecosystem.
Essentially, we must look toward the smallest and most ignored among us to understand our future on this planet.
The last two years have witnessed a sequencing revolution, and there
is no doubt that in the next two years, we will see a computational revolution to cope with the sequence data
