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
33/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
This Illumina HiSeq 2000 amplicon dataset from human gut metagenome samples provides 39.6 million reads and 7.8 billion bases with moderate quality (78.7% Q20, 63.5% Q30) at 55.7% GC content, supporting microbial community composition analysis and relative-abundance estimation. The amplicon-based approach resolves operational taxonomic units suitable for diversity profiling and treatment-response studies across individuals. Reusers should account for quality metrics limiting low-abundance taxon detection and de novo assembly compared to shotgun metagenomics approaches.
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.
