What this means
claude:haiku

Illumina Genome Analyzer II short-read RNA-seq of Melitaea cinxia (Glanville fritillary butterfly) with 5.1 million reads at moderate quality (Q30=83.6%) across 455 million bases. Despite moderate base quality and lower read count, the dataset supports targeted gene expression studies in this butterfly model, particularly for population and evolutionary genomics.

How this grade was computed
Weighted mean of 4 scored metric(s) → 84/100

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.
