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
100/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
This 454 GS FLX Titanium amplicon dataset from sponge metagenome generates ~820K reads (~376 Mb) with moderate quality (97.4% Q20, 91.1% Q30), representing legacy environmental amplicon data. The 454 platform is now discontinued, and data quality is moderate for modern standards. Researchers interested in historical metagenomics or legacy sequencing will find this relevant.
The A 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
