Annotation of DO Identifiers to their Children

Description

This data set describes associations between DO terms and their direct children terms, based on the directed acyclic graph (DAG) defined by the Disease Ontology Consortium. The format is an R object mapping the DO terms to all direct children terms, where a direct child term is a more specific DO term that is immediately preceded by the given DO term in the DAG.

Details

Each DO term is mapped to a vector of children DO terms.

Mappings were based on data provided by: Disease Ontology With a date stamp from the source of: 20150323 (sub_version 2806)

Examples

  # Convert the object to a list
  xx <- as.list(DOCHILDREN)
  # Remove DO IDs that do not have any children
  xx <- xx[!is.na(xx)]
  
  if(length(xx) > 0){
     # Get the parent DO IDs for the first elents of xx
        doids <- xx[[1]]
        # Find out the DO terms for the first parent doid
        DOID(DOTERM[[doids[1]]])
        Term(DOTERM[[doids[1]]])
        Synonym(DOTERM[[doids[1]]])
        Secondary(DOTERM[[doids[1]]])
