Deep data QC

Escherichia coli O104:H4 hybrid short+long WGS via 454 GS FLX Titanium yields 12.3M reads with very low quality (18.2% ≥Q20, 2.1% ≥Q30), indicating severely compromised base accuracy. Poor quality severely impairs variant calling and de novo assembly quality; investigate platform issues or investigate purification protocols before reuse in critical analyses.
The F 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.
