In Topological Tree Analyszer user-defined expressions are used to calculate the actual data (e.g., distances between trees) from basic topological values. A set of functions is available to formulate such expressions and to access the basic values. An unlimited number of user expressions can be defined and will be written to a results table at the end of an analysis. It is also possible to reference results from one user expression from another one and reuse the result there.
