From: Three dimensional approach to investigating biological effects along energetic ion beam pathways

(a) S. cerevisae cells irradiated with a 20 Gy dose. (b) S. cerevisae cells irradiated with a 500 Gy dose. (c) C. vulgaris cells irradiated with a 20 Gy dose. (d) C. vulgaris cells irradiated with a 500 Gy dose. Heatmap and cluster analyses were performed according to the heatmap method (HemI 1.0.1—Heatmap Illustrator) described by Deng W. et al.43. In this paper, option parameters were as follows. Normalization, Linear (default); Clustering, Hierarchical—Average linkage (default); Similarity Metric, Pearson distance (default); Bar, Discrete bar. Statistical significance between each experimental group and the control is denoted as: *Representsp < 0.05, **p < 0.01, ***p < 0.001.
