Deep data QC
67/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
This Illumina NextSeq 550 amplicon-seq from SARS-CoV-2 comprises 1.9 million reads totaling 551 million bases at very good quality (97% ≥Q20, 95% ≥Q30). The minimal N content and 38.7% GC composition reflect clean amplicon library preparation. This targeted amplicon dataset enables rapid viral variant identification for surveillance, though amplicon-based sequencing limits full-genome coverage and the modest read depth constrains rare variant detection.
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.
