\begin{Description}\relax
This data set describes associations between GO molecular function (MF)
terms and their direct children 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 direct children terms, where a
direct child term is a more specific GO term that is immediately preceded
by the given GO term in the DAG.
\end{Description}
\begin{Details}\relax
Each GO MF term is mapped to a vector of children 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

    if(length(xx) > 0){
        # Get the children GO identifiers for the first elents of xx
        goids <- xx[[1]]
