Hi BioC Users, How to find which GeneChip to load from BioC library by reading Probe ID's  from .CSV file? e.g. if I read a  .csv file and i get probe id: 221666_s_at and how can I find which GeneChip to load from BioC libaray. Requirements: 1) .csv file does not have any other info. other than probeids. 2) R/BioC is running in BATCH mode in back-ground. Any one had this kind of problem before ? Thank you in advance, Saurin [[alternative HTML version deleted]]
