Deep data QC

43/100 · F

Standardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured

What this means

claude:haiku

454-platform amplicon metagenome with poor base quality. Q30=72.8% (scored 14/100) fails; 98.88% duplication and platform limits make this unsuitable. Evidence_strength=1 confirms measured failure.

How this grade was computed

Weighted mean of 2 scored metric(s) → 43/100

The F 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.
