Hi all, I am - not very successfully - playing with AnnBuilder and would appreciate any comments on the error I am getting (system info below). Confusingly, the same code *seems* to work fine on my windows machine, only here I don't want to deal with unzipping problems. Sorry if this is something obvious. platform x86_64-unknown-linux-gnu arch x86_64 os linux-gnu system x86_64, linux-gnu status major 2 minor 7.1 year 2008 month 06 day 23 svn rev 45970 language R library(hgu133plus2.db) x=hgu133plus2ENTREZID xx=as.list(x) basefile=data.frame(names(xx),as.character(unlist(xx))) write.table(basefile,"Basefile.txt",sep="\t",row.names=F) library(AnnBuilder) mySrcUrls=getSrcUrl("all",organism="Homo sapiens") ABPkgBuilder(baseName = read.table("Basefile.txt",header=F,sep="\t"), srcUrls = mySrcUrls, baseMapType ="ll", pkgName = "hgu133plus2", pkgPath = getwd(), organism = "Homo sapiens", version = "1.1.0",author = list(authors = "K"),fromWeb=TRUE) Error in validObject(.Object) : invalid class "UG" object: invalid object for slot "baseFile" in class "UG": got class "data.frame", should be or extend class "character" Calls: ABPkgBuilder ...

If so, then instead of AnnBuilder, please use the SQLForge functions inside of AnnotationDbi to make custom annotation packages. This will allow you to make a more modern ".db" style annotation package. You can find the instructions here: http://www.bioconductor.org/packages/2.3/bioc/html/AnnotationDbi.html If you have further questions, please feel free to ask, Marc
