\title{Map custom probeset IDs to gene start position}
\description{
 gahgu95cGENESTART is an R environment that provides mappings between a
 custom probeset identifier and the base pair starting position of gene onto corresponding chromosome.
}
\details{
  Each identifier maps to a gene start position.
  If the gene start position is unknown,
  the vector will contain an \code{NA}.

  Mappings were based on data provided by:
  
  GeneCards database - www.genecards.org

        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
            # Get the base pair number for gene start position for the first five probes
