GO annotations are represented as classes. In order to understand what these classes are, we need to first see what the source material for the annotoations is. This image from Amigo shows the basic information. A gene is named, with the underlying identifier from Entrez Gene, a gene ontology term is named, from one of Cellular Component, Biological Process, or Molecular function, there is an "evidence code" that gives some indication of the manner in which the annotation was inferred, and citation of one or more papers.



We need to interpret this information in a manner that is consistent with the rest of the Neurocommons representation. The source files for the annotations are obtained from the EBI and their format is documented. We've converted human, mouse, and rat annotation - the files we use are:


 * gene_association.goa_human
 * human.xrefs
 * gene_association.goa_mouse
 * mouse.xrefs
 * gene_association.goa_rat
 * rat.xrefs

(CORRECTION: Currently we only have GO annotations from NCBI - not from EBI.)

The following illustration shows how the annotation is to be interpreted.



To what does the annotation refer?
