Dear All, I was wondering if anyone can please advice me! I am trying to analyse a set of NimbleGen MeDIP-chip data using Ringo and ACME packages. I need some advice on how to export/use the normalised data from Ringo for further analysis in ACME package. I have used the preprocess function in Ringo to generate an ExpressionSet object (the normalised data) see below. normdata <-preprocess(RG,method="nimblegen") Many thanks, Adeolu [[alternative HTML version deleted]]
