Map between Manufacturer Identifiers and UniGene cluster identifiers

Description

OperonHumanV3UNIGENE is an R object 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 ) on 2008-Apr2

Examples

        x <- OperonHumanV3UNIGENE
        # Get the probe identifiers that are mapped to an UNIGENE ID
        mapped_probes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_probes])
        if(length(xx) > 0) {
          # Get the UNIGENE for the first five probes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
