hu6800UNIGENE mappes probe identifiers to UniGene cluster identifiers
This an environment object with key and value pairs. Keys are probe ids and values are the corresponding UniGene cluster ids. Values may be vectors of length 1 or greater depending on whether a given probe id can be mapped to only one or more UniGene cluster ids. NA is assigned to probe ids that can not be mapped to any UniGene cluster id at this time.
Mappings were based on data provided by:
