How do I create embedded regions like the mesoderm and endoderm in the sea urchin endomesoderm network?
Every node or gene in a top-level instance model belongs to one and only one regular region. However, BioTapestry also allows the user to define any number of subregions within a regular region, where a node or gene in the region can belong to any number of subregions. For example, in the following piece of the endomesoderm model, the Endomesoderm region has two defined subregions: the Endoderm and the Mesoderm.
