     gahgu95cGO2PROBE is an R object that provides mappings between GO
     identifiers and probesets.

_D_e_t_a_i_l_s:

     Each GO term maps to a named vector of probesets. The name
     associated with each probeset corresponds to the evidence code for
     that GO identifier. The evidence code indicates what kind of
     evidence supports the association between the GO and Entrez Gene
     identifiers. Evidence codes currently in use include:

     IMP - inferred from mutant phenotype

     IGI - inferred from genetic interaction

     IPI - inferred from physical interaction  

     ISS - inferred from sequence similarity  

     IDA - inferred from direct assay  

     IEP - inferred from expression pattern  

     IEA - inferred from electronic annotation  

     TAS - traceable author statement  

     NAS - non-traceable author statement  

     ND - no biological data available  

     IC - inferred by curator

     A GO identifier may be mapped to the same probe identifier more
     than once but the evidence code can be different. Mappings between
     Gene Ontology identifiers an Gene Ontology terms and other
     information are available in a separate data package named GO. 

     Mappings were based on data provided by:

     Genecards ( http://www.genecards.org ) on 2009-mag06
