## Map Manufacturer identifiers to GenBank Accession Numbers

### Description

Roberts2005AnnotationACCNUM is an R object that contains mappings between a manufacturer's identifiers and GenBank accession numbers.

### Details

This object 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.

Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2008-Sep2

### Examples

            x <- Roberts2005AnnotationACCNUM
            # Get the probe identifiers that are mapped to an ACCNUM
            mapped_probes <- mappedkeys(x)
            # Convert to a list
            xx <- as.list(x[mapped_probes])
            if(length(xx) > 0) {
              # Get the ACCNUM for the first five probes
              xx[1:5]
              # Get the first one
              xx[[1]]
            }
