Fig. 1.

Graphical representation of K-means clusters of 1,037 BATS-determined NSI-Het genes (a) and 1,762 BATS-determined NSI-Hrm genes (b). The x axis shows time (in h), and the y axis, M, shows the log₂(experimental) − log₂(reference) values. Minimum and maximum M values on the y axis are different in each plot to allow better visualization of the extent of statistically significant differentially transcribed genes. The red lines highlight where 0 lies on the y axes. The number of genes within each cluster is indicated in the upper left corner of each plot.
