Harry, I'm working with the devel version of pdInfoBuilder and am updating/adding components for building Gene ST pdInfo objects. Coincidently I'm building the pdInfo object for the Affy RaGene-1_0 array. I should have this complete in the next couple of days and can forward it on to you if you'd like, or provide the script necessary to build. I will update the devel version once its ready.
