Provenance — who produced it, who reused it

Linked to 1 papers in the literature. Roles are inferred factual signals (who deposited the data vs who reused it), with counts — never a judgement about any author.

Deep data QC

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

What this means

claude:haiku

Human amplicon. Completely failed run unsuitable for reuse (grade F, score 0/100). Dual catastrophic failures: Q30 at only 46.5% (scored 0/100) and adapter contamination at 53.76% (scored 0/100)—>50% adapter content indicates a sequencer or library prep failure.

How this grade was computed

Weighted mean of 2 scored metric(s) → 0/100

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.
