What this means

claude:haiku

Nannochloropsis oceanica WGS on 454 GS FLX Titanium with 21.7M reads at lower quality (46.1% ≥Q20, 46.1% ≥Q30). Lower-accuracy legacy platform dataset for marine microalgae genome assembly; requires stringent quality filtering.

How this grade was computed

Weighted mean of 3 scored metric(s) → 46/100

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.
