\title{Map between Manufacturer Identifiers and UniGene cluster identifiers}
\description{
   hs25kresogenUNIGENE is an R object that provides mappings between
   manufacturer identifiers and UniGene identifiers.
}
\details{
  Each manufacturer identifier is mapped to a UniGene identifier. An \code{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: Entrez Gene  
  ftp://ftp.ncbi.nlm.nih.gov/gene/DATA
