## Annotation of GO Identifiers to their Biological Process Ancestors

### Description

This data set describes associations between GO Biological Process (BP) terms and their ancestor BP terms, based on the directed acyclic graph (DAG) defined by the Gene Ontology Consortium. The format is an R object mapping the GO BP terms to all ancestor terms, where an ancestor term is a more general GO term that precedes the given GO term in the DAG (in other words, the parents, and all their parents, etc.).

### Details

Each GO BP term is mapped to a vector of ancestor GO BP terms.

Biological process is defined as the broad biological goals, such as mitosis or purine metabolism, that are accomplished by ordered assemblies of molecular functions 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 200708

### Examples

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