## Map FlyBase CG accession numbers with manufacturer identifiers

### Description

drosgenome1FLYBASE is an R object that contains mappings between manufacturer identifiers and FlyBase CG accession numbers. These accessions are used by Ensembl and supported by FlyBase.

### Details

This object is a simple mapping of manufacturer 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-Sep2

### Examples

        x <- drosgenome1FLYBASECG
        # Get the manufacturer IDs that are mapped to a Flybase CG ID
        mapped_genes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_genes])
        if(length(xx) > 0) {
          # Get the FlyBase CG IDs for the first five genes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
        #For the reverse map FLYBASECG2EG:
        # Convert to a list
        xx <- as.list(drosgenome1FLYBASECG2PROBE)
        if(length(xx) > 0){
           # Gets the manufacturer IDs for the first five FlyBase CG IDs
           xx[1:5]
           # Get the first one
           xx[[1]]
        }
