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.

Fecal metagenome amplicon-seq via Ion Torrent PGM produces 3.2 billion bases (18.9 million reads) with moderate quality (68.4% Q30 bases), characteristic of non-Illumina short-read platforms. The Ion Torrent approach offers different sequencing chemistry and potential biases compared to Illumina; useful for validating Illumina-based microbiome findings or as an independent orthogonal assay.
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.
