Deep data QC

454 GS FLX+ pyrosequencing amplicon data from leaf microbiota yields 440.6 million bases across 601k reads with 70.5% Q20 and elevated N-content (0.137%). Medium-length reads (typical ~400bp) and lower accuracy offset by reduced cost; suitable for preliminary phylogenetic profiling of plant phyllosphere communities.
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.
