[BioC] Bioconductor cdf package for Arabidopsis?

[Hua Liu]

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
