What this means

claude:haiku

Escherichia coli str. K-12 MinION long-read WGS with only 39.6 million bases across 5,639 reads—shallow coverage and extremely poor base quality (3.7% Q20, 0.9% Q30). Insufficient for assembly, variant calling, or gap closure. Represents a failed or minimally successful nanopore run; not suitable for biological inference.

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.
