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

16S rRNA amplicon sequencing of bovine (cattle) gut metagenome via 454 GS FLX Titanium long-read platform with ~216k reads spanning ~115 Mb. This dataset enables long-read amplicon profiling of ruminant microbiota at high taxonomic resolution, particularly valuable for detecting rRNA length variants that define species boundaries in anaerobic bacteria. Long-read sequencing captures the full 16S gene length for improved phylogenetic accuracy.
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.
