i am trying to create a CDF file for the affymetrix tiling array (S. cerevisiae) - this is what i did: >library(pdInfoBuilder) >pkg=new("AffyTilingPDInfoPkgSeed", version="0.1", author="ddd", biocViews="AnnotationData", bpmapFile="Sc03b_MF_v04.bpmap", cifFile="Sco3b_MF_v04.cif", email="..... at .....") >makePdInfoPackage(pkg, destDir=".") and at this point - i get this error message: Error in gsub(nm[i], symbolValues[[i]], res) : invalid argument am stuck - can anyone please help me with pointer to proceed forward? Thanks a ton. Warm regards, k -- Only as high as I reach can I grow, Only as far as I seek can I go, Only as deep as I look can I see, Only as much as I dream can I be.

Hi Karthikeyan, Can you please give us the output of sessionInfo() ? You might find the following posting guide helpful too: http://www.bioconductor.org/docs/postingGuide.html As for the package pdInfoBuilder, I can tell from the call you listed that whatever version you are using is not the most recent one. One of the changes is that the newer package is much better documented. You might want to try out the latest development version of this package as things have improved a lot. And, just in case you don't like the idea of using devel, there will be a released version April 21st.
