What this means

claude:haiku

Whole-genome WGS of D. melanogaster using Genome Analyzer IIx, producing 19 million reads at 40× coverage with moderate base quality (83.1% Q30). This legacy WGS dataset enables variant calling and genomic comparisons within the reference assembly.

How this grade was computed

Weighted mean of 4 scored metric(s) → 89/100

The B 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.
