What this means

claude:haiku

Drosophila melanogaster WGS on Genome Analyzer yields ~1.77 billion bases at 12.7x coverage with poor quality (72.6% Q20, 0% Q30). This early fly dataset requires extensive filtering.

How this grade was computed

Weighted mean of 4 scored metric(s) → 37/100

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.
