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
45/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
This 454 GS FLX amplicon dataset from an environmental metagenome contains 9.4 million reads with 73.6% Q30 bases, serving as a legacy dataset for method benchmarking and historical microbiome platform comparison. Researchers validating bioinformatic pipelines or studying 454 sequencing characteristics will find data demonstrating platform-specific read patterns and quality profiles. The lower quality scores require stringent filtering before OTU/ASV clustering and taxonomic assignment.
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.
measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0
