What this means

claude:haiku

Butterfly bulk RNA-seq with balanced limitations. Grade B (87/100) shows competing issues: duplication at 63.84% (scored 25/100) and minor adapter content (2.39%), with quality metrics around acceptable thresholds (Q30 92.2%). The duplication is the primary concern—expression estimates will lose resolution, especially at moderate abundance levels.

How this grade was computed

Weighted mean of 4 scored metric(s) → 87/100

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.
