Hello all, I have a custom chip and I'm following the directions at: http://www.bioconductor.org/repository/devel/vignette/makecdfenv.pdf to try to make a CDF for my custom chip, and running into some troubles. When i try to run make.cdf.env i have the following message : " Reading CDF file. Error in getInfoInFile(file, "CDF", unit = "Chip", property = "Name", : Cannot open the file C:/Program Files/R/rw2001/myfile.cdf." I would probably need some additional tools to get it working, but i don't know wich one to install. Thanks, Malick, --------------------------------- mails !

Is the cdf file really in your R_home directory, or is it somewhere else? If so, you need to either change your working directory to the location of the cdf file, or you need to explicitly state the location in your call to make.cdf.env(). One other possibility (if the cdf is where R is looking), is that the cdf is in binary format. You can test this by opening the cdf using WordPad. If you can't read anything, it is binary. Affy is changing from text to binary format for the cdf files, and we don't yet have the functions to handle the binary format. Binary compatibility is being worked on, and should be done soon.
