Hello All,
I am fairly new to processing exon array CEL files using the Affy package in Bioconductor and I was trying to obtain RMA values for 6 chips on the Human Exon 1.0 st array and I received the following error message after the rma command was run:
> eset<-rma(data)

Error in getCdfInfo(object) :
  Could not obtain CDF environment, problems encountered:
Specified environment does not contain HuEx-1_0-st-v2
Library - package huex10stv2cdf not installed
Bioconductor - could not connect
In addition: Warning message:
In readLines(biocURL) :
  cannot open: HTTP status was '503 Service Unavailable'

I am under the impression that exon arrays have different library files than the traditional cdf files used for the IVT expression arrays.  The 4 library files for the exon array exist with the following extensions:  .mps, .clf, .pgf, .qcc.  Is there something special needed for processing exon arrays in bioconductor?
Thank you,
Jennifer
