Hello, I have some problems with the gcrma normalization procedure. Please look at the output: ---- > Chips.norm<-gcrma(Chips.raw) Adjusting for optical effect............................Done. Computing affinities.Error in get(x, envir, mode, inherits) : variable "mouse4302dim" was not found > traceback() 9: get(nam) 8: get("NROW", get(nam)) 7: xy2indices(p$x, p$y, cdf = cdfpackagename) 6: inherits(x, "factor") 5: is.factor(x) 4: match(xy2indices(p$x, p$y, cdf = cdfpackagename), pmIndex) 3: compute.affinities(cdfName(object), verbose = verbose) 2: bg.adjust.gcrma(object, affinity.info = affinity.info, affinity.source = affinity.source, NCprobe = NCprobe, type = type, k = k, stretch = stretch, correction = correction, GSB.adjust = GSB.adjust, rho = rho, optical.correct = optical.correct, verbose = verbose, fast = fast) 1: gcrma(Chips.raw) ---- I'm using R Version 2.5.1 and Bioconductor 2.0. I've reinstalled all needed packages, but I noticed no difference in the behavior. The same procedure worked with previous versions of R and Bioconductor though. It's possible to circumvent the problem? On reply, please CC me as I'm not subscribed to the list. Thanks in advance! Bye, Sebastian

Hi Sebastian, Please always give us the output of sessionInfo() as well. Just telling us you have BioC 2.0 isn't sufficient. For instance, I get this to work: > dat <- ReadAffy(filenames=list.celfiles()[1:5]) > eset <- gcrma(dat) Adjusting for optical effect.....Done. Computing affinities.Done. Adjusting for non-specific binding.....Done.

Hi James, James W. MacDonald wrote: > Please always give us the output of sessionInfo() as well. Just telling > us you have BioC 2.0 isn't sufficient. For instance, I get this to work: Thanks for your quick reply. You sessionInfo() output gave me the hint that I did not update some of the annotation packages whose existence I wasn't aware of (initially, I updated only the mouse4302 package) :) After updating the rest, all seems to work again. However, from an user's point of view, I would rather like to see an appropriate error message coming up which complains about non-matching versions of the required package. Is there such a mechanism in Bioconductor/R? Ciao, Sebastian

Hi Sebastian, I don't know if there is a method to check for mis-matched packages, but there is a simple way to update your packages so in truth there should be no need for such checking. If you update your R version, all you need to do is then install all needed packages using biocLite(). If for whatever reason you haven't used biocLite() to install the packages, you can always use update.packages(): biocLite("Biobase") ##ensure Biobase is correct version library(Biobase) repos <- biocReposList() update.packages(repos=repos, ask=FALSE) If you follow either prescription then you should never have to worry about mis-matched packages. If you do something else, then you are on your own ;-D Best, Jim Sebastian Bauer wrote: > Hi James, > > James W. MacDonald wrote: >> Please always give us the output of sessionInfo() as well.
