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
61/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
This metagenome amplicon dataset from 454 GS FLX Titanium generated 3.9 million reads (2.05 gigabases) with 90.3% Q20 and 78.3% Q30 base quality, and 54.1% GC. The lower Q30 rate and elevated N-content (2.12%) are characteristic of 454 pyrosequencing; suitable for taxonomic profiling of mixed microbial communities despite technical limitations.
The D 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.
