Deep data QC

This 454 GS FLX Titanium bulk RNA-seq dataset from Cercophonius squama (spider) comprises 59,174 reads and 35 million bases with moderate quality (87.9% Q20, 64.9% Q30), representing limited transcriptome sampling. The 49.3% GC is characteristic; the shallow depth suggests enrichment for abundant transcripts rather than comprehensive transcriptomics. Reusers should recognize incomplete coverage and treat this as a candidate-gene discovery resource rather than quantitative expression-profiling across all expressed loci.
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.
