 3. Run desired system years described by (1) UKMOD, using the (2) "b" series dataset - note that the same input data set should be used for all system years. System runs can be performed directly in UKMOD or calling UKMOD from STATA, R, or Python using the respective connectors.
 4. Copy the files generated following (3) to model directory: `SimPaths/input/EUROMODoutput/`. Please note that it is required to provide UKMOD output files which include the base price year used by SimPaths (currently 2015). If no UKMOD output file is provided for the base price year, the initial database setup will fail.
 5. Run SimPathsStart, and selection option "Load new input data for tax and benefit systems" from the Start-up Options window.
