I was wondering if there is some way of getting the XPS package working at gene level as I need to get the gene expression from some Rat Gene chips (RaGene 1.0 ST r4)that I will analyze. I tried to use the Affy package before but as far as I understand they need .CDF file to get working and I only have CLF and PBG files for my chips.

I created some CDF-files for these chips that you can also use (not sure on the r4 though): http://nmg-r.bioinformatics.nl/NuGO_R.html Regards, Dr. Philip de Groot Bioinformatician / Microarray analysis expert Wageningen University / TIFN Netherlands Nutrigenomics Center (NNC) Nutrition, Metabolism & Genomics Group Division of Human Nutrition PO Box 8129, 6700 EV Wageningen Visiting Address: "De Valk" ("Erfelijkheidsleer"), Building 304, Verbindingsweg 4, 6703 HC Wageningen Room: 0052a T: 0317 485786 F: 0317 483342 E-mail: Philip.deGroot at wur.nl I:???????? http://humannutrition.wur.nl https://madmax.bioinformatics.nl http://www.nutrigenomicsconsortium.nl -----Original Message----- From: Benilton Carvalho [mailto:beniltoncarvalho@gmail.com] Sent: zaterdag 2 juni 2012 12:20 To: Jorge Mir?

Dear Jorge, You can preprocess both, RaExon and RaGene 1.0 ST arrays, at the probeset and the gene level, simply set the option to either option="probeset" or to option="transcript", e.g.: data.rma <- rma(data.genome ,"RaGeneRMAMetacore", filedir=datdir background="antigenomic", normalize=TRUE, option="transcript", exonlevel="metacore+affx") See the help file ?rma. For further examples see the scripts "script4exon.R" and "script4xps.R" in the xps/examples directory. See also script "script4schemes.R" how to create the scheme for the RaGene array.
