Popis: Pathway Analysis is used as a selection method to determine which reaction rate coefficient uncertainties need to be included for the uncertainty analysis, as a fast alternative for sensitivity analysis. This requires the Pathway Analysis implementation to include the analysis of the electron power density. Results from Pathway Analysis as a selection method are compared with results from sensitivity analysis. For a nitrogen chemistry we show the agreement in results between Pathway Analysis and sensitivity analysis, and additionally results of the uncertainty analysis. We also apply the method to a CO$_2$ chemical system that involves vibrationally excited states to demonstrate the excellent performance of this method for complex systems.
