Hi, I have some RAE230 B chips and want to stick them through GCRMA. The metadata for the RAE230A and RAE2302 chips looks fine, but the probe data for RAE230B seems to be identical at RAE230A. At present I'm getting Error in getGroupInfo(object) : Probe sequence information not available. Please download and install the rae230bprobe library from: http://www.bioconductor.org/data/metaData.html Does anybody have a working rae230bprobe library?
