AmiGO 2 Manual: Search
This page gives some examples of advanced queries in AmiGO 2
Annotations
For ontology queries, start at http://amigo2.berkeleybop.org/cgi-bin/amigo2/amigo/search
Motivation: epithelial cells are often regarded to be eumetazoan innovations. Here we use AmiGO 2 to explore this hypothesis and check for potential errorsin GO.
- Start at http://amigo2.berkeleybop.org/cgi-bin/amigo2/amigo/search - the starting point is all annotations
- Type: epithel in the filter box to the left of the results. The results are very inclusive - anything that matches this string in any field, or descendent of term that matches this string. Approx ~10k annotations
- Open "taxon" facet
- Select "-" next to bilateria
Explore the results using the left and right arrows. At the time of writing there are some obvious erroroneus annotations - can you spot them? You can filter out the IEA using the "evidence" filter.
Gene Products
- Start at http://amigo2.berkeleybop.org/cgi-bin/amigo2/amigo/search - then select "gene products"
- Type "limb morphogenesis" in the filter field
- Open "involved in" and click "+" on "limb morphogenesis"
- ...
Ontology
For ontology queries, go to http://amigo2.berkeleybop.org/cgi-bin/amigo2/amigo/search And select "Ontology"
All obsolete terms in subsets
Motivation: ontology subset maintainers may wish to check if there are stale terms in subsets
- Start at http://amigo2.berkeleybop.org/cgi-bin/amigo2/amigo/search
- Select "Ontology" tab
- Open "subset" facet
- Select a GO slim - e.g. goslim_prok (note: some will be from other ontologies; use the "source" facet to eliminate these)
- Open "obsoletion" facet - you can see the distribution between obsolete / non-obsolete. Select "+" next to "true" (or "-" next to false)
Note you can also explore boolean combinations of slims - e.g. terms in both yeast and prok slim
