I want to analyse the data with the limma package, but for that I need to built my own CDF package, probe package and built the filters to analyse one specie or another. I'm using the makeProbePackage available in the AnnotationDbi (for a R-2.13.0) but I got the following error message: Error in rep(NA, max(pm1, mm1, pm2, mm2)) : invalid 'times' argument I already tried an old version of R-2.9.1 with a package matchprobes (that is no longer update for R-2.13.0) but the same error occur...

Naively using makecdfenv's make.cdf.package() causes R to seg-fault. I'm unfamiliar with the CDF format as such, but I'm guessing that it's changed somewhat because the PM arrays no longer have P/A and mismatches. I'm looking to build
