Merge Procedure

Merging Ontology Terms

What is a GO term merge?

Term merges result from two or more terms being subsumed into a single term.

When are GO terms merged?

Common reasons to merge terms include:

  • Terms have exactly the same meaning
  • The meaning is too close to support consistent, distinct annotations
  • The distinction between a parent and a child is not useful or necessary in the scope of GO

What happens when GO terms are merged?

When terms are merged, e.g. term A and term B are merged into term A, the GO ID of term B is made an alternative (secondary) GO ID, and the term string is made a synonym. Secondary GO IDs remain in GO with the 'alt_id' tag.
