Dear Vincent, Spot on. Many Thanks. Works fine now. Wondering if at all there is a way to create genome plots per sample (23 plots per chromosome) but showing gains and losses per sample through all chromosomes ? Many Thanks, --E From: Vincent Carey [mailto:stvjc@channing.harvard.edu] Sent: 30 March 2012 17:56 To: Ekta Jain Cc: bioconductor@r-project.org Subject: Re: [BioC] DNAcopy for CNV in SNP Affy 6.0 Somewhat unlikely that you will get much help using an R 2.9.1 -- please upgrade to 2.14.1, install with biocLite, and try again.

As given in the manual, i have created my CNA.object by reading a file for chromosome, position and values for one sample. When performing smoothed.CNA.object <- smooth.CNA(CNA.object) I get the following error: > smoothed.CNA.object <- smooth.CNA(CNA.Object) Error in if (xi > max(xnbhd) + oSD) xi <- median(c(xi, xnbhd)) + sSD : missing value where TRUE/FALSE needed In addition: Warning message: In max(xnbhd) : no non-missing arguments to max; returning -Inf I will highly appreciate if someone can tell me where could i be possibly going wrong?

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.
