What this means

claude:haiku

Illumina Genome Analyzer IIx whole-genome sequencing of Drosophila melanogaster generating 6.8 billion bases at estimated 48.8x coverage with lower Q30 quality (79.3%) than companion datasets. While adequate for many applications, the quality profile warrants independent validation before use in sensitive downstream analyses requiring high base accuracy.

How this grade was computed

Weighted mean of 4 scored metric(s) → 83/100

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.
