I am trying to get copy number estimates for Illumina 660W-Quad and CytoSNP-12 bead arrays with package crlmm. I have successfully read in the *.idat files. But when continuing the crlmmIllumina function requires the specification of a chip description file. Are these files yet available somewhere? All I have are the manifest files (*.bpm) from GenomeStudio. Regards, Christian

Hi Christian, I'm glad to hear you were able to read in the data OK. You will need a chip specific package to proceed further, and as yet I haven't made any of these available on BioC (beta versions are sitting around on my harddrive). I'll let you know as soon as they are online.
