[BioC] DNAcopy for CNV in SNP Affy 6.0

[Ekta Jain]

Dear BioC Help,
I am having issues with the CGHcall package when using in R. I first employ DNAcopy package to smooth and segment my data (CNA.object) and get an error while performing post normalize processing using the CGHcall package.

> smoothed.CNA.object <- smooth.CNA(CNA.object)
> segment.smoothed.CNA.object <- segment(smoothed.CNA.object, verbose=1) 
Analyzing: ABC1 
Analyzing: BEN
> postseg.cghdata <- postsegnormalize(segment.smoothed.CNA.object)
Error in function (classes, fdef, mtable)  : 
  unable to find an inherited method for function "segmented", for signature "DNAcopy"

Is there any structural difference between CNA object and CGH object type? Please do let me know where i could possibly be going wrong.

Thank you,
Ekta
