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

What this means

claude:haiku

Human gut amplicon survey from a 454 GS FLX Titanium platform with 1 million long reads at 81% Q30. The longer reads provide better taxonomic resolution of 16S rRNA gene sequences compared to short-read platforms.

How this grade was computed

Weighted mean of 2 scored metric(s) → 71/100

The C 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.
