Hi
 
Any suggestions how to map  gene symbols to mouse EntrezId(preffered) or
Affy. 
mapping to Entez apparently is not supported by GSEABase
> mapIdentifiers(gss,EntrezIdentifier())
Error in .mapIdentifiers_isMappable(from, to) : 
  unable to map from 'Symbol' to 'EntrezId'
    neither GeneIdentifierType has annotation
Error in GeneSetCollection(lapply(what, mapIdentifiers, to, ..., verbose
= verbose)) : 
  error in evaluating the argument 'object' in selecting a method for
function 'GeneSetCollection'
 
 
Mapping to Affys works for human, but not for mouse
> mapIdentifiers(gss, AnnotationIdentifier("hgu95av2.db"))
GeneSetCollection
  names: chr5q23, chr16q24 (2 total)
  unique identifiers: 35089_at, 35090_g_at, ..., 35807_at (79 total)
  types in collection:
    geneIdType: AnnotationIdentifier (1 total)
    collectionType: BroadCollection (1 total)
> mapIdentifiers(gss, AnnotationIdentifier("mouse4302.db"))
GeneSetCollection
  names: chr5q23, chr16q24 (2 total)
  unique identifiers:  (0 total)
  types in collection:

Thanks
