Hi, I was trying to run this : http://www.aroma-project.org/howtos/createCdfFromBioconductorPlatformDesignInfo/ to create a mighty cdf file for HuGene-2_0-st affymetrix array from this bioconductor annotation package <http://www.bioconductor.org/packages/release/data/annotation/html/pd.hugene.2.0.st.html> .
When running the example code (after installing the appropriate packages) : library("aroma.affymetrix") library("pd.hugene.1.0.st.v1") pathname <- writeCdf(pd.hugene.1.0.st.v1, tags = "pd.hugene.1.0.st.v1,HB20110111", overwrite = TRUE) I obtained this error: > pathname <- writeCdf(pd.hugene.1.0.st.v1, tags= "pd.hugene.1.0.st.v1,HB20110111", overwrite=TRUE) Loading required namespace: pdInfoBuilder Generating CDF file from Platform Design (PD) package...

Is it the writeCdf function from affxparser package? 2) affxparser::writeCdf first parameter is fname and not pathname. Hence the error? writeCdf(fname, cdfheader, cdf, cdfqc, overwrite=FALSE, verbose=0) 3) aroma is loading affxparser itself, and is masking the writeCdf function: Loading required package: affxparser Attaching package: âaffxparserâ The following object is masked from âpackage:aroma.affymetrixâ: writeCdf and the annotation package: Attaching package: âoligoâ The following object is masked _by_ package:aroma.affymetrix: writeCdf Reversing the order of package loading did not solved the issue. I am having the same issue when generating the cdf for the HuGene-2_0-st array.
