\title{Mappings between probe identifiers and the PubMed identifiers for
  the publication where functional annotation of genes corresponding to
  the probe ids were made}
\description{
  NCBI
  \url{http://www.ncbi.nlm.nih.gov/projects/GeneRIF/GeneRIFhelp.html}
  allows users to add functional annotation of genes by providing a
  PubMed identifier for the publication where the annotation was initially
  made and a concise phrase describing the function. hgu2beta7GRIF maps
  probe identifiers to the PubMed identifiers for the publication
  reporting the functions of genes corresponding to the probe identifiers
}
\details{
  Probe ids are only mapped to the PubMed ids. Efforts are being made to
  also include the concise phrase describing the function of a gene.  
  
  Mappings were based on data provided by:
