Deep data QC
98/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Whole-genome sequencing of Escherichia coli with excellent measured base quality (Q30=93.4%, mean=37.1) achieving A-grade status. However, mean coverage at 127.1× is extrapolated rather than directly measured, provisionally lowering confidence—a deep measured pass confirming uniform coverage across the genome is pending before committing to population genetics or low-frequency variant detection.
The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published WGS thresholds, weighted by its importance; nothing is hidden or subjective.
measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0
