## Map between Manufacturer Identifiers and UniGene cluster identifiers

### Description

hguatlas13kUNIGENE is an R environment that provides mappings between manufacturer identifiers and UniGene identifiers.

### Details

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:

Entrez Gene:ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/. Built: Source data downloaded from Entrez Gene on Thu Mar 15 17:38:49 2007

### Examples

        # Convert the environment to a list
        xx <- as.list(hguatlas13kUNIGENE)
        # Remove probe identifiers that do no map to any UniGene id
        xx <- xx[!is.null(xx)]
        if(length(xx) > 0){
            # The UniGene identifiers for the first two elements of XX
            xx[1:2]
            # Get the first one
            xx[[1]]
        }
