It is now the 3rd CHALLENGE Period for CACAO Fall 2017! It will end on Sunday October 22, 2017 at 11:59 pm CDT
This is your chance to challenge other team's annotations. You may also DEFEND or suggest improvements to your own annotations IF they have been challenged. Please note, although we ENCOURAGE challenges, an excess of identical challenges that do not appear to be applicable to the annotation or well thought out will be considered spam and ignored.

the intercollegiate annotation competition!
The Community Assessment of Community Annotation with Ontologies (CACAO) is a competition for teams of undergrads around the world to improve the functional annotation of genes. CACAO was developed and is currently run at Texas A&M University, along with many other institutions. If you are interested in participating, please email us -

  • Don't forget - no binding terms (i.e. DNA binding, etc) & no response to terms (i.e. response to heat, etc)

Evidence codes you are permitted to choose from

  • Here's a list of the evidence codes that CACAO students may use:
  1. IDA: Inferred from Direct Assay
  2. IMP: Inferred from Mutant Phenotype
  3. IGI: Inferred from Genetic Interaction - requires with/from field to be filled in
  4. ISO: Inferred from Sequence Orthology - requires with/from field to be filled in
  5. ISA: Inferred from Sequence Alignment - requires with/from field to be filled in
  6. ISM: Inferred from Sequence Model - requires with/from field to be filled in
  7. IGC: Inferred from Genomic Context

ALL other codes, even if used correctly, will cause the annotation to be rejected by the judges

Virus-related GO terms
