What this means

claude:haiku

Uncultured bacterium amplicon 454 sequencing with grade B quality (82/100). Long reads (mean 453.5 bp) support taxonomic resolution, but Q30 84.7% and extreme duplication 97.61% are notable; while high duplication is typical for PCR amplicons, it may overrepresent abundant sequence variants without computational deduplication.

How this grade was computed

Weighted mean of 2 scored metric(s) → 82/100

The B 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.
