Deep data QC
53/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Bioreactor metagenome, 454 amplicon sequencing; grade F—unsuitable as-is. Duplication rate of 93.97% means nearly all reads are PCR clones, rendering true-variant detection impossible; Q30 of 76% compounds the problem by adding baseline sequencing errors on top of amplification bias.
The F 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.
