Mappings between probe identifiers and UniGene cluster identifiers

Description

NCBI partitions sequences submitted to GenBank into non-redundant sets of clusters. Each cluster contains sequences that represent a unique gene and is assigned a unique UniGene id. hgu95av2UNIGENE maps probe identifiers to UniGene cluster identifiers for genes represented by the probe ids

Details

A UniGene id represents a cluster of sequences of a gene. Using UniGene ids one can query the UniGene database for information about the sequences or the LocusLink database for information about the genes.

Mappings were based on data provided by:

Examples

    # Convert the environment to a list
    xx <- as.list(hgu95av2UNIGENE)
    # Remove probe ids that do no map to any UniGene id
    xx <- xx[!is.null(xx)]
    if(length(xx) > 0){
        # The UniGene ids for the first two elements of XX
        xx[1:2]
        # Get the first one
        xx[[1]]
    }
