What this means

claude:haiku

Short-read Illumina amplicon of SARS-CoV-2. Grade D (69/100, marginally better than peers): not recommended for reuse without preprocessing. Adapter contamination at 13.97% (scoring 7/100, weight 0.5) is lower than most SARS-CoV-2 amplicons but still warrants trimming; high duplication (92.36%) remains problematic.

How this grade was computed

Weighted mean of 2 scored metric(s) → 69/100

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.
