Deep data QC
100/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
16S rRNA amplicon survey of human gut microbiome sequenced on Illumina MiSeq with 6 million reads (2.9 billion bases), demonstrating consistent high quality (97.3% Q20, 95.7% Q30) and no N-content contamination. Suitable for alpha and beta diversity analysis and bacterial taxonomy assignment in intestinal communities; the 56.1% GC reflects typical human fecal microbiota composition. The clean, high-fidelity data stream enables direct OTU or ASV workflow without quality gatekeeping.
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.
