-Some of these functions are also explained in this {{ :tutorials:grogra_reference_guide.pdf | initial GROGRA documentation }} (page 98f.) and some further expansions in this {{ :tutorials:dzierzon_et_al_2003.pdf | paper}} (https://doi.org/10.14214/sf.510). This wiki provides a compressed form of the information in these sources, which are outdated. Not all the functions mentioned in the GROGRA documentation are 1:1 available in GroIMP. Also some of the the features of the different functions appear to be broken or they don't work at all (at least with the basic RGG model tree). This is because they were designed for some specific purpose that was lost over time. So use them at your own discretion. You can also check out the source code of the functions [[https://gitlab.com/grogra/groimp-plugins/RGG/-/blob/master/src/main/java/de/grogra/grogra/Analysis.java?ref_type=heads | here]].

 ==== Topological analysis ====
+Number of components, number of (graph-theoretical) links, maximal and average topological depth and other topological parameters, see {{ :tutorials:oppelt_kurth_godbold_2001.pdf | Oppelt et al. (2001)}}
