## Map Manufacturer identifiers to GenBank Accession Numbers

### Description

u133x3pACCNUM is an R environment that contains mappings between a manufacturer's identifiers and GenBank accession numbers.

### Details

This environment was produced by first mapping the manufacturer's identifiers to Entrez Gene identifiers http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene. The mapped Entrez Gene identifiers then serve as the point of linkage to the GenBank accession numbers.

Each manufacturer identifier maps to a vector containing a GenBank accession number.

### Examples

            # Convert to a list
            xx <- as.list(u133x3pACCNUM)
            # Remove probe identifiers that do not map to any ACCNUM
            xx <- xx[!is.na(xx)]
            if(length(xx) > 0){
            # Get the ACCNUM for the first five probes
            xx[1:5]
            # Get the first one
            xx[[1]]
    }
