     indacUNIGENE is an R environment that provides mappings between
     manufacturer identifiers and UniGene identifiers.

_D_e_t_a_i_l_s:

     Each manufacturer identifier is mapped to a UniGene identifier. An
     'NA' is reported if the manufacturer identifier cannot be mapped
     to UniGene at this time. 

     A UniGene identifier represents a cluster of sequences of a gene.
     Using UniGene identifiers one can query the UniGene database for
     information about the sequences or the Entrez Gene database for
     information about the genes.  

     Mappings were based on data provided by:
