Fig. 5From: Between-species differences in gene copy number are enriched among functions critical for adaptive evolution in Arabidopsis halleri Distribution of signal intensities before and after normalization and scaling. Boxplot of (a) background-corrected raw hybridization signal intensities, (b) normalized signal intensities after VSN normalization of the replicate arrays of each species, respectively, and (c) signal intensities after the application of species-specific global scaling factors to the normalized data. Boxes show median, and upper and lower quartiles, of L o g 2 probe signal intensities for each gDNA hybridization. Upper and lower horizontal bars mark all values lying within 1.5 times the inter-quartile range. Replicate hybridizations are denoted 1 and 2 and grouped by speciesBack to article page
