What this means

claude:haiku

SARS-CoV-2 amplicon short-read data (Grade F)—the lowest-quality dataset in this cohort. Highest adapter contamination (29.03%) combined with notably reduced base quality (84.2% Q30+) severely compromises utility. High duplication (84.18%) and poor overall metrics make this unsuitable for reuse without substantial re-processing or re-sequencing.

How this grade was computed

Weighted mean of 2 scored metric(s) → 47/100

The F 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.
