Hi All, I am interested in using a reduced number of probe sets of HG- U133plus2, for example masking some probe sets, to run RMA for my data analysis. I guess that I should make all new .CEL files from the original data sets and a new .cdf file which is modified to fit my new data sets. I am wondering if there are some easy ways with BioC to achieve that? Do I have to write some codes with, e.g. Perl, to make the new data sets and a new cdf? Any suggestions and help will be greatly appreciated!

At least as far as rma() goes you may supply a vector of probeset names using the subset argument. eg library(affy);library(affydata);data(Dilution) goodprobesets <- geneNames(Dilution)[1:10] eset <- rma(Dilution,subset=goodprobesets) eset On Tue, 2005-04-19 at 13:17 -0400, Jianping Jin wrote: > Hi All, > > I am interested in using a reduced number of probe sets of HG- U133plus2, > for example masking some probe sets, to run RMA for my data analysis.
