What this means

claude:haiku

SARS-CoV-2 amplicon short-read data (Grade D). Despite excellent base quality (96.9% Q30+), high adapter contamination (25.95%) indicates systemic amplicon preparation issues—adapter purity is critical for amplicon work. Severe duplication (91.31%) compounds the problem; reuse requires aggressive trimming and inspection for off-target signal.

How this grade was computed

Weighted mean of 2 scored metric(s) → 67/100

The D 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.
