Statistical tests between two or more groups for called aCGH data. The testing is recommended to be performed after running the Identify common regions from called aCGH data tool.
Perform statistical testing between groups for differences in copy number aberrations. Three different test statistics are available for the p-value calculations. The significance of the p-values is evaluated by permuting the sample groups, and a false discovery rate is calculated. At least 10,000 permutations are recommended for final calculations, and this will require a significant amount of time.
The input table appended with loss/gain/amplification frequencies for the different groups, along with p-values and false discovery rates.
