GEDI whole-genome transcriptional status of the samples exposed to different g* and B fields. A 20 × 16 clustering analysis is shown based on the five magnetic experimental conditions (first row panels) and the two mechanical experimental conditions (third row panels) versus the external 1 g control. The panels in the second row have been calculated by extracting the 1 g* panel values (only magnetic effect) from the g* panels immediately above. The vertical colour scale bar indicates the average log2ratio levels of each cluster in the conditions compared to the parallel 1 g control (first and third row) or versus the 1 g* control (second row). The average signal in experimental conditions is slightly higher than the 1 g control (log2ratio equal to 0.03 in the centre of the scale bar) suggesting overall up-regulation. Double up-regulated clusters (with an average log2ratio > 1.03) are saturated to red and those half down-regulated (average log2ratio < -0.97) are saturated to blue. Clusters in between follow a continuous colour scale as indicated. The centre panel indicates the number of probe sets included in each cluster (20 × 16 clusters with an average size of 54 probe sets per pixel) following its own horizontal scale at the bottom.
