Effect of sub-sampled read depth on the standard deviation of target gene hits in the sub-sampled metagenome relative to the full metagenome. The target gene was beta-galactosidase, mapped using a custom database of beta-galactosidase sequences. The metagenomes tested were a an infant fecal metagenome of 30 million merged reads, b all infant fecal metagenomes of at least 10 million merged reads, and c adult fecal metagenomes with at least 20 million unmerged reads mapped using the congruent strategy
