Hello Anguraj, you can impute missing values before segmentation with preprocessing functions in snapCGH or CGHcall packages. Check their vignettes.

That leads to missing probes after segmentation. But I require all the probes after segmentation. Any thoughts how I can get DNAcopy to provide all the probes after segmentation? Any help will be appreciated.
