Deep data QC
100/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Human gut microbiome amplicon sequencing achieves perfect A-grade QC (100/100) with zero adapter contamination and acceptable base quality (Q30=90.5%). Duplication rate of 73.98% is extremely high and reflects amplicon assay design (constrained target diversity), not sequencing failure—expect limited ability to discriminate rare variants and OTU abundance estimates biased toward dominant taxa. Suitable for detection of major community members; reuse requires acknowledgment of duplication limitations.
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.
