Reticulate Nexus Block Schematic. Shown is a schematic of the Reticulate nexus block as it is implemented in SplitsTree. The block is divided into three parts: the Dimensions contains all information about the dimensions of the reticulate network; the Format is an optional element that describes the configuration of the reticulate network; and the TreeComponents, NettedComponents and RootComponents contain the string representation of the reticulate network.
