     drosophila2GO is an R environment that provides mappings between
     manufacturer ids and GO ids.

_D_e_t_a_i_l_s:

     Each manufacturer id is mapped to a named vector of GO ids. The
     name associated with each GO id corresponds to the evidence code
     for that GO id. 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

     Mappings between probe ids and GO information were obtained
     through their mappings to Entrez Gene ids. NAs are assigned to
     probe identifiers that can not be mapped to any Gene Ontology
     information. 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:
