What this means

claude:haiku

E. coli WGS on AB SOLiD 4hq System; 47.2M color-space reads achieve exceptionally high coverage (513.3×) but with poor quality (Q30 35.2%), indicating early SOLiD instrument limitation. Massive depth cannot compensate for low per-base accuracy; primarily historical interest for method development.

How this grade was computed

Weighted mean of 4 scored metric(s) → 53/100

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.
