Several existing projects, such as the RCSR or Epinet , aim at collecting the different nets underlying the structure of real or hypothetical crystals. This is key to allowing researchers to create new materials with a target topology, which is useful to obtain specific physical properties, given the strong link between materials topology and properties for a given chemical composition . However, in order to check the accuracy of the collected nets with regard to existing crystals, one needs a way to determine the net from a given crystal structure.
