     indacGO2PROBE is an R environment that provides mappings between
     GO identifiers and manufacturer identifiers.

_D_e_t_a_i_l_s:

     Each GO term maps to a named vector of manufacturer identifiers.
     The name associated with each manufacturer identifier 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:
