     YEASTGO2PROBE is an R environment that provides mappings between
     GO ids and manufacturer ids.

_D_e_t_a_i_l_s:

     Each GO term maps to a named vector of manufacturer ids. The name
     associated with each manufacturer id corresponds to the evidence
     code for that GO id. The evidence code indicates what kind of
     evidence supports the association between the GO and Entrez Gene
     ids. 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 id may be mapped to the same probe id more than once but the
     evidence code can be different. Mappings between Gene Ontology ids
     an Gene Ontology terms and other information are available in a
     separate data package named GO. 

     Mappings were based on data provided by:

     LocusLink Yeast Genome: Not available.
