From: Assessment of urban microbiome assemblies with the help of targeted in silico gold standards
Composition of an in silico gold standard. The process of replacing classified bacterial reads with in silico reads obtained from known reference genomes is depicted. The resulting gold standard contains all unclassified sequences together with any non-bacterial sequences, while sequences classified as bacterial are replaced by in silico reads or, in case no reference genome could be assigned, are dropped
