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.
1 further paper cites this accession but reuse could not be confirmed.
Deep data QC

Plant metagenome, 454 long-read amplicon; grade F—marginal for OTU profiling. Q30 of 75.2% contributes significant sequencing error to taxonomy assignment; duplication rate of 94.46% reflects PCR-driven amplification bias. Combined effect makes confidence in abundance estimates low without deep replicates.
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.
