Hierarchical clustering of gene expression data of parabolic flight samples from parabola 1 (A) and 31 (B). Independent samples cluster together based on the subjected acceleration irrespective of the flight day for both parabolas. (A) For parabola 1, µg (grey bars) and 1.8 g-2 (green) show close resemblance as well as 1 g (blue) and 1.8 g-1 (red). (B) In parabola 31, clusters appear for 1.8 g-2 (green) and 1 g (blue) as well as µg (grey) and 1.8 g-1 (red). Hierarchical clustering was performed based on normalized intensity values using Pearson uncentered correlation and Wards linkage rules. At least three independent samples for each acceleration from different flight days were employed for hierarchical clustering.
