org.Dm.egFLYBASECG {org.Dm.eg.db} | R Documentation |
org.Dm.egFLYBASE is an R object that contains mappings between Entrez Gene identifiers and FlyBase CG accession numbers. These accessions are used by ensembl and supported by flybase.
This object is a simple mapping of Entrez Gene identifiers http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene to Flybase CG accession numbers.
Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2008-Apr2
