I'm helping someone analyze array data from the ArrayStar lncRNA 2.0 microarrays. The company claims that they can't or won't provide annotations for every probe on the array, since that information is proprietary. They will only provide it for probes that they found to be differentially expressed in their own analyses based on things you asked them to contrast when you initially purchased the array service from them.
However, the company has created two platform description files in GEO (GPL13825 and GPL15314) that contain the full sequences of the probes they are using. Presumably, someone could BLAST those sequences agaiunst the genome and then create their own set of annotations.
Question 1: Has anyone used the ArrayStar GPL files to construct their own annotation database? If so, can you supply a copy?
Question 2: Is anyone interested in helping put together such an annotation database and contributing it to BioConductor?
