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 profiling of human gut microbiota via Illumina MiSeq, comprising 9.3 million reads across 4.5 billion bases with exceptional quality metrics (97.5% Q20, 95.7% Q30) and zero N content. Provides high-confidence compositional and diversity data for gut bacterial ecosystems; the elevated 57.5% GC content reflects Firmicutes and Bacteroidetes dominance in fecal samples. Superior read quality minimizes filtering steps and supports sensitive detection of low-abundance taxa and rare community members.
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.
