16S rRNA amplicon sequencing of human gut microbiome via MiSeq with ~16M short reads but notably poor quality (only 48.1% Q30, despite 0% N content), representing a problematic dataset. This dataset requires extensive quality filtering before reliable taxonomic assignment, and researchers should consider the limited usability for sensitive ecological inference. The low Q30 rate suggests either amplicon chimera artifacts or sequencing instrument issues.
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.
