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
Unclassified ssDNA viral amplicon survey from 454 GS FLX Titanium yields only 87K reads with moderate accuracy (88.4% ≥Q20, 68.3% ≥Q30), providing shallow viral community snapshot. Low read depth limits ecological inference and abundance estimation; best reused for presence/absence assays or rare-viral-species discovery rather than quantitative comparisons.
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.
