Deep data QC
100/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
16S amplicon survey of fecal microbiota via Illumina MiSeq, producing 778,000 reads and 468 million bases with high quality (97.4% Q20, 92% Q30) and no N content. Characterizes intestinal bacterial communities with strong sequence fidelity; the 53.3% GC reflects typical fecal microbiota composition. Moderate read count provides adequate depth for compositional and diversity profiling; the excellent Q30 supports reliable taxonomy assignment without aggressive trimming.
The A 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.
