B. Clustering according to the Ratio method; green = ratio ≥ 0.65 (. good), red = ratio < 0.65 (. degraded), and black = N/A (. not available). C. Clustering according to the RIN method; green = RIN ≥ 6 and red = RIN < 6. Arrows indicate samples clustering in an unexpected manner, according to the respective methods
