Groups with common expression profiles.
Each graph corresponds to a hierarchical clustering of transcripts. X-axis: Clone 1 samples at 0 and 48 hpi, clone 2 at 0 and 48 hpi. Y-axis: centered median of log2 (FPKM). The blue line corresponds to the average expression values per group. Gray lines represent individual transcripts. The number of transcripts per group is shown in the upper left part of each graph.
