16S rRNA amplicon sequencing of human gut microbiome via MiSeq with only ~4.4M reads but notable quality concerns (77.2% Q30 and 0.4% N content). This dataset enables basic taxonomic profiling of gut bacterial communities but the moderate quality and modest read depth limit sensitivity for rare taxa detection. Researchers should apply stringent quality filtering before taxonomic assignment and consider the dataset may be underpowered for detecting subtle community differences.
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.
