Mean vs median dye swap plots. Each panel shows log2 fold changes from the same two dye-swapped arrays. The effect of choosing mean or median to summarize spot intensity is seen by comparing across rows. Background correction methods can be compared across columns. Mean or median dye swap correlation is similar. Both pre and post-normalization, correlation from highest to lowest is no background adjustment, minimal constant adjustment and local background subtraction.
