Deep data QC
67/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Short-read Illumina amplicon of SARS-CoV-2. Grade D: not recommended for reuse. Adapter contamination at 23.61% (scoring 0/100) will degrade variant calls despite good Q30 bases (96.6%); high duplication (91.25%) adds to the effective coverage loss.
The D 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.
