This 454 GS FLX Titanium amplicon dataset from human samples contains 157,717 reads with exceptional base quality (97.2% Q20/Q30), capturing microbial community composition via longer-read amplicon sequencing. Researchers performing microbiome profiling or requiring taxonomic resolution for human-associated bacteria will benefit from this legacy dataset demonstrating high-fidelity 454 amplicon sequencing. The dataset is suitable for species-level classification and comparative microbiome studies against contemporary platforms.
The A 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.
