What this means

claude:haiku

SARS-CoV-2 amplicon sequencing; marginal quality (grade D). Two compounding liabilities reduce confidence: high adapter contamination (25.13%, scored 0/100) and lower Q30 content (88.4%, scored 92/100), both degrading variant calling sensitivity and introducing noise. This combination makes the dataset risky for reuse without independent re-trimming and fresh QC verification.

How this grade was computed

Weighted mean of 2 scored metric(s) → 61/100

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.
