What this means
claude:haiku

This Helicoverpa armigera bulk RNA-Seq dataset from the Illumina HiSeq 2000 platform contains 22 million short reads (4.39 billion bases) with very good quality (92.3% Q20, 86.8% Q30 bytes). The high-quality reads enable robust expression profiling of this agricultural pest. Search terms: lepidopteran transcriptomics, HiSeq 2000, cotton pest genomics, insect development, applicable to pest management and insecticide resistance studies.

How this grade was computed
Weighted mean of 4 scored metric(s) → 93/100

The A 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.
