What this means
claude:haiku

Short-read bulk RNA-seq from maize (Zea mays, likely same experiment as SRR039506). Grade F; Q30 61.8% and mean base quality 28.3 fail expression standards, suggesting library degradation. Short 35 bp reads and low base quality limit mapping reliability and transcript quantification. Paired failure; reuse not recommended.

How this grade was computed
Weighted mean of 4 scored metric(s) → 35/100

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.
