## Annotation of GO Identifiers to their Molecular Function Offspring

### Description

This data set describes associations between GO molecular function (MF) terms and their offspring MF terms, based on the directed acyclic graph (DAG) defined by the Gene Ontology Consortium. The format is an R object mapping the GO MF terms to all offspring terms, where an ancestor term is a more specific GO term that is preceded by the given GO term in the DAG (in other words, the children and all their children, etc.).

### Details

Each GO MF term is mapped to a vector of offspring GO MF terms.

Molecular function is defined as the tasks performed by individual gene products; examples are transcription factor and DNA helicase as defined by Gene Ontology Consortium.

Mappings were based on data provided by: Gene Ontology ( ftp://ftp.geneontology.org/pub/go/godatabase/archive/latest ) on 200803

### Examples

      # Convert the object to a list
      xx <- as.list(GOMFOFFSPRING)
      # Remove GO identifiers that do not have any offspring
      xx <- xx[!is.na(xx)]
      if(length(xx) > 0){
        # Get the offspring GO identifiers for the first two elents of xx
      goids <- xx[1:2]
      }
