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
83/100 · BStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
16S amplicon sequencing from human metagenome on 454 GS FLX Titanium platform generating longer reads than contemporary short-read technology. This older-platform microbiome dataset enables microbial community profiling and serves as a historical reference for comparing 454 versus Illumina amplicon methodologies in human-associated samples.
The B 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.
