What this means

claude:haiku

Illumina Genome Analyzer IIx whole-genome sequencing of Drosophila melanogaster with 4.6 billion bases, achieving perfect Q20/Q30 quality and an estimated 33.2x genome coverage. The dataset is well-suited for assembly validation, variant calling, and population-level genomic studies despite being from an older sequencing platform.

How this grade was computed

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

The A 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.
