What this means

claude:haiku

Butterfly bulk RNA-seq with strong per-base quality offset by high duplication. Grade B (85/100) relies on excellent Q30 (95.8%) and mean quality (37.7), but 69.17% duplication (scored 13/100) signals the same library complexity issue as SRR900572. High-quality reads do not rescue duplicate-driven bias—expression estimates will be unreliable without explicit duplicate collapsing.

How this grade was computed

Weighted mean of 4 scored metric(s) → 85/100

The B grade is a transparent weighted average. Each metric below scored from 0–100% against the published bulk-RNA-seq thresholds, weighted by its importance; nothing is hidden or subjective.
