Deep data QC
96/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Human gut 16S amplicon with deep sequencing. Strong QC (96/100, A) supported by Q30 of 88.8% and zero adapters, but an extreme duplication rate of 98.29% indicates nearly all reads are PCR replicates rather than biological diversity—this severely undermines the ability to assess true microbial community composition. Use only for abundance profiling in samples known to have limited diversity, or apply heavy PCR-duplicate filtering.
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.
