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.

Deep data QC
33/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Whole-genome amplification (WGA) sequencing of Escherichia coli BL21 (a common laboratory strain) via MiSeq with ~8.5M short reads at moderate quality (81.5% Q30). This dataset captures amplified genomic DNA from a widely-used protein expression host, useful for strain comparison and laboratory stock verification. The WGA-induced bias and lower Q30 rate warrant careful quality filtering before variant calling or assembly.
The F grade is a transparent weighted average. Each metric below scored from 0–100% against the published WGS thresholds, weighted by its importance; nothing is hidden or subjective.
