Deep data QC

Latrodectus hesperus (black widow spider) full-length cDNA RNA-seq from Genome Analyzer IIx with 17M reads at moderate quality (80.4% Q20, 50.3% Q30). FL-cDNA sequencing captures full-transcript length information valuable for isoform discovery in this understudied arachnid. Moderate Q30 is acceptable for abundance estimation; lower Q30 may complicate high-confidence variant calling.
The F grade is a transparent weighted average. Each metric below scored from 0–100% against the published bulk-RNA-seq thresholds, weighted by its importance; nothing is hidden or subjective.
