What this means

claude:haiku

This NovaSeq 6000 amplicon dataset for SARS-CoV-2 contains 3.04 million short reads (887.8 million bases) with excellent quality (99% Q20, 96.5% Q30) and zero N-content. The 38.7% GC content is consistent with SARS-CoV-2 expectations. High quality and solid read depth support confident variant calling and consensus sequencing; suitable for large multiplexed surveillance with sustained coverage per amplicon.

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.
