To perform a Source Search, a user specifies a set of source structures. The service returns all experiments for which either the primary injection structure or one of its secondary injection structures corresponding to one of the specified source structures or their descendents in the ontology. The search results can also be filtered by a specified list of transgenic lines.Example:

See the connected service page for definitions of service::mouse_connectivity_injection_structure parameters.

Examples:

• Source search for experiments with injection in the isocortex

• Source search for experiments performed on wild-type specimens and injection in the isocortex

• Source search for experiments performed on Syt6-Cre_KI148 cre-line with injection in the isocortex

  Code Block
  http://api.brain-map.org/api/v2/data/query.xml?criteria= service::mouse_connectivity_injection_structure[injection_domain$eqIsocortex][transgenic_lines$eq'Syt6-Cre_KI148']

The output of the source search is a xml list of objects. Each object represents one experiment and contains information about the experiment identifier, the primary injection structure, list of any secondary injection structures, injection coordinates, injection volume and transgenic line name.

• Visualize source search in the web application

Figure: Screenshot of source search results in the web application for experiments with injection in the isocortex. The injection location of each experiment is shown as a sphere on the 3D injection map.
