What this means
claude:haiku

This Melitaea cinxia (Glanville fritillary butterfly) bulk RNA-seq from a NextSeq 500 yielded 6.2 million short reads (944.1 million bases) with solid quality (95.8% Q20, 94.1% Q30). The 42.5% GC content fits this lepidopteran species' transcriptome profile and supports gene expression quantification and transcriptomic studies. The read count and sequencing depth suit differential expression analysis in moderately replicated multi-group designs.

How this grade was computed
Weighted mean of 4 scored metric(s) → 94/100

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.
