Deep data QC
45/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Enterobacterales amplicon profiling via 454 GS FLX Titanium yields ~1M reads with moderate accuracy (89.7% ≥Q20, 73.4% ≥Q30), supporting taxonomic classification of cultured bacterial isolate communities. 454 read length provides phylogenetic resolution for marker genes; lower Q30 necessitates abundance filtering to mitigate false-positive variants and chimeras.
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.
