What this means

claude:haiku

Oxford Nanopore long-read WGS data (Cereibacter sphaeroides), grade F due to catastrophic base quality (Q30 12.5%, mean Q15.6), which is disqualifying for any analysis. Even with zero adapters and minimal duplication, quality this poor prevents reliable variant calling or assembly. Data is unsuitable for reuse; likely sequencer failure or protocol issue.

How this grade was computed

Weighted mean of 3 scored metric(s) → 47/100

The F grade is a transparent weighted average. Each metric below scored from 0–100% against the published WGS thresholds, weighted by its importance; nothing is hidden or subjective.
