Human gut metagenome amplicon-seq on MiSeq spans 7.4 billion bases (12.3 million reads) with moderate quality (82.4% Q30 bases), providing reasonable depth for microbiota profiling. The dataset captures amplicon variation across samples; moderate quality suits typical 16S/18S abundance surveys where minor sequencing errors do not significantly affect taxonomic assignment.
The F grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
