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
68/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
SARS-CoV-2 amplicon data with moderate-to-high adapter contamination (14.47%, measured) limiting reuse despite robust sequencing depth (3M reads). Grade D reflects adapter contribution of only 4/100 points (weight 0.5); Q30=90.2% indicates acceptable sequencing quality but cannot offset primer carryover. Reuse requires explicit adapter removal and post-trim QC.
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.
