What this means
claude:haiku

D. melanogaster WGS from Genome Analyzer IIx with 5.8B bases and 41.5× coverage but notably lower quality (73.8% Q30) than other IIx runs, suggesting end-run or chemistry drift. The reduced accuracy is acceptable for population-level variant detection and small indel discovery but compromises fine-scale structural analysis. Pair with higher-quality D. melanogaster datasets for robust variant consensus.

How this grade was computed
Weighted mean of 4 scored metric(s) → 74/100

The C 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.
