     hu6800UNIGENE mappes probe identifiers to UniGene cluster
     identifiers

_D_e_t_a_i_l_s:

     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:
