Deep data QC
45/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
454 GS FLX Titanium WGS of the plant Fritillaria alfredae subsp. glaucoviridis yielded 101k long reads totaling 28.8 Mb with moderate quality (66–87% bases at Q20–Q30) typical of pyrosequencing chemistry and 35.6% GC. The long-read format suits structural variant discovery and de novo assembly of plant genomes, though the moderate base-level accuracy benefits from supplementary short-read polishing and is challenging for SNP-level reuse.
The F grade is a transparent weighted average. Each metric below scored from 0–100% against the published WGS thresholds, weighted by its importance; nothing is hidden or subjective.
