Use event logs
You can use specific event logs for your analyses, for example, a modified default event log as the basis for your calculations. By default, only the default event log is available and automatically used as the basis for all your analyses. If you created custom event logs, the event logs are provided in the 
Event log drop-down menu in your analyses.
All your analyses are based on the currently activated event log that is preselected in the Event log menu. However, you can select a different event log to be applied to the current analysis on an ad-hoc basis. If you close and reopen the analysis, or reload the browser tab, the activated event log is applied again.
