KEfED model for a tract-tracing experiment. A KEfED model for a generic tract-tracing experiment as shown in the KEfED editor. The workflow provides a high-level view of the provenance over the course of the complete experimental protocol starting with experimental subject (in this case, a rat) through the material processing that generates experimental material that may be analyzed to generate data (in the form of an account of the presence of histological labeling of varying density and type at different locations in the brain).
