 # Benchmark Problems for Dynamic Modeling of Intracellular Processes
-A collection of ODE models with experimental data as benchmark problems in order to evaluate new and existing methodologies for data-based modeling.
+A collection of ODE models with experimental data as benchmark problems in order to evaluate new and existing methodologies for data-based modeling. A preprint for the introduction and analysis of the benchmark problem collection is available at https://www.biorxiv.org/content/early/2018/08/30/404590.
 
 The benchmark models were export from Data2Dynamics (https://github.com/Data2Dynamics/d2d), version of Aug 17th 2018, commit tag f27f9fd554fd23f9c048239172fafc6686a27fe0.
 Export can be repeated by compiling the respective model within the 'Example' folder, followed by call of 'arExportBenchmark'
