## Map Entrez Gene identifiers with FlyBase Acession numbers

### Description

indacFLYBASE is an R object that contains mappings between Entrez Gene identifiers and FlyBase accession numbers.

### Details

This object is a simple mapping of Entrez Gene identifiers http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene to Flybase Accession Numbers.

Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2007-Aug23

### Examples

        x <- indacFLYBASE
        # Get the entrez gene identifiers that are mapped to a FLYBASE ID
        mapped_genes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_genes])
        if(length(xx) > 0) {
          # Get the FlyBase IDs for the first five genes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
        # For the reverse map:
        # Convert to a list
        xx <- as.list(indacFLYBASE2PROBE)
       if(length(xx) > 0){
           # Get the probe identifiers for the first five IDs
           xx[1:5]
           # Get the first one
           xx[[1]]
        }
