[BioC] simpleAffy QC on HT_HG-U133_Plus_PM

[Michael Walter]

Dear all,

I'm trying to use the simpleAffy QC functions to look at some HT_HG-U133_Plus_PM arrays which are not recognized automatically. So I followed the vignette and created a config file which looks like follows:

array hthgu133pluspmcdf
alpha1 0.05 
alpha2 0.065 
spk bioB AFFX-r2-Ec-bioB-3_at 
spk bioC AFFX-r2-Ec-bioC-3_at 
spk bioD AFFX-r2-Ec-bioD-3_at 
spk creX AFFX-r2-P1-cre-3_at 
ratio actin3/actin5 AFFX-HSAC07/X00351_3_at AFFX-HSAC07/X00351_5_at 
ratio actin3/actinM AFFX-HSAC07/X00351_3_at AFFX-HSAC07/X00351_M_at 
ratio gapdh3/gapdh5 AFFX-HUMGAPDH/M33197_3_at AFFX-HUMGAPDH/M33197_5_at 
ratio gapdh3/gapdhM AFFX-HUMGAPDH/M33197_3_at AFFX-HUMGAPDH/M33197_M_at 

I save the file as "hthgu133pluspmcdf.qcdef in the same folder as all the default config files. 

When I try to analyse the Affy batch I get following error message:

>data <- ReadAffy(celfile.path=celfile, filenames=filenames)
>path2QCenv = "C:/Programme/R/R-2.9.0/library/simpleaffy/extdata"
>setQCEnvironment(cleancdfname(cdfName(data)),path2QCenv)
>qc.cel <- qc(data)
Fehler: NAs in externem Funktionsaufruf (arg 1)

So I'd would highly appreciate any hints, where to look for my mistake.

Thank you very much.

Kind regards, 

Michael
