What this means
claude:haiku

Gut metagenome amplicon sequencing via Illumina MiSeq with 35.4 million reads and 21.3 billion bases at moderate quality (93.5% Q20, 87.4% Q30). The 53.3% GC and 1,149 files suggest large-scale human microbiota sampling across many individuals or time points. This deep dataset enables robust diversity analyses and discovery of compositional signatures associated with disease or treatment.

How this grade was computed
Weighted mean of 2 scored metric(s) → 91/100

The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
