From: Normalization of array-CGH data: influence of copy number imbalances

Figure 1

Genome plot and M-A plot representing two frequently used ways of visualizing aCGH data. Plots show data from the L56Br-C1 xenograft [19] analyzed using a tiling 32 K BAC array and illustrate how copy number imbalances readily observed in genome plots can be difficult to discern as copy number populations in M-A plots. (a) M-A plot of un-normalized data. (b) Genome plot of un-normalized data.
