I want to study the probel level data from Affymetrix Arabidopsis Genome ATH1 Array. I loaded the agcdf pachage, but the folloing R result shows that agcdf does not match this new Arabidopsis ATH1 array: > data<-ReadAffy("f:/doc/agl15/WS-1_ATH1.CEL") > data AffyBatch object size of arrays=712x712 features (3963 kb) Error in .local(object, ...) : Information about probe locations for ATH1-121501 could not be found. Try downloading the ath1121501cdf package from http://www.bioconductor.org/data/cdfenvs/cdfenvs.html Is there a cdf package that is suitable for this array? Thanks, Liu

if you have the cdf file, you can use the package makecdfenv to make you own. if you do bioconductor would appreciate you contribute it.
