Searching the ChEBI ontology

The ChEBI ontology can be searched using "Filter by Ontology Term" on the ChEBI Advanced Search Page (Figure 17).

  • Select a desired relationship (e.g. is a, has role etc.) from the drop-down menu of "Select relationship";
  • Enter the ontology term (e.g. fatty acid, alcohol etc.) into the ontology search box. When entering the ontology term into the ontology search box, it is important to type in a few characters, allow time for possible matches to be suggested, then to select the desired term from the suggested list (type a few more characters one at a time if the desired term isn't on the initially-suggested list).
  • Extra relationships can be added/removed by using the plus/minus tabs adjacent to query fields.
