Mappings between KEGG pathway identifiers and probe identifiers


KEGG (Kyoto Encyclopedia of Genes and Genomes) maintains pathway data for various organisms. Each pathway has a name, pathway id, and graphical presentation of the pathway. rae230aPATH2PROBE maps KEGG pathway ids to probe identifiers representing genes whose products participate in the interactions of the pathway


Pathway name for a given pathway id can be obtained using the KEGG data package that can either be built using AnnBuilder or downloaded from Bioconductor http://www.bioconductor.org.

Graphic presentations of pathways are searchable at url{http://www.genome.ad.jp/kegg/pathway.html} using pathway ids as keys.

Mappings were based on data provided by:

KEGG:ftp://ftp.genome.ad.jp/pub/kegg/pathways. Built: Release 31.0 (July 2004)

LocusLink:ftp://ftp.ncbi.nih.gov/refseq/LocusLink/LL_tmpl.gz. Built: September 15, 2004

    # Remove pathway ids that do not map to any probe id
    xx <- xx[!is.na(xx)]
    if(length(xx) > 0){
        # The probe ids for the first two elements of XX
        # Get the first one
