Hello, given the several requests I got re: supporting HTA 2.0 chips when using oligo, I'm posting this message to bioc (rather than bioc-devel). I'll add support for HTA on our next release. A draft is ready through the devel branch. I may need to make some adjustments prior to the April release. For those interested in giving it a try, you'll need to have a developer installation of Bioconductor (please, make sure to use a different path to set your library and avoid mixing & matching). Then install oligo v. 1.27.3. With the devel bioc installed, you can use the usual: biocLite('oligo') You will also need an annotation package specific for HTA, which you can download from here: (source version only) https://dl.dropboxusercontent.com/u/83643/pd.hta.2.0_3.8.0.tar.gz After downloading the annotation package, install it using: ## assuming that you loaded R from the directory where the ## package was downloaded to. install.packages('pd.hta.2.0_3.8.0.tar.gz', repos=NULL) Once both are installed, you should be able to run the standard: library(oligo) cels = list.celfiles() raw = read.celfiles(cels) pp0 = rma(raw, target='core') pp1 = rma(raw, target='probeset') to obtain your preprocessed data through oligo. The annotation package will be made available through Bioconductor in the next few weeks (devel branch again). If you're in the mood of building your own annotation package, after ensuring you have the aformentioned packages (and versions) installed, also install pdInfoBuilder (version 1.27.4). Then, you can use the template below to create your package: ## code to build HTA annot pkg library(pdInfoBuilder) seed <- new("AffyHTAPDInfoPkgSeed", version="3.8.0", license="Artistic-2.0", pgfFile=dir(patt=".pgf$"), clfFile=dir(patt=".clf$"), probeFile=dir(patt="probeset.csv$"), transFile=dir(patt="transcript.csv$"), coreMps=dir(patt=".mps$"), geneArray=TRUE, author="Benilton Carvalho", email="beniltoncarvalho@gmail.com", biocViews="AnnotationData", genomebuild="hg19", organism="Homo sapiens", species="Homo sapien", url="http://about.me/benilton") makePdInfoPackage(seed, destDir=".") ## end If you have any feedback/comment, please contact me. benilton [[alternative HTML version deleted]]
