 +====== Group Equal Instances in a Log ======
 +
 +Sometimes it is useful to pre-process a log in the sense that process instances exhibiting the same event sequence are aggregated in one instance indicating their number of occurrences using the "​numSimilarInstances"​ attribute within the //Data// section of the //​ProcessInstance//​ tag. 
 +
 +This aggregation can be achieved using a dedicated export plug-in available in ProM. Simply choose //Exports -> [log] -> Grouped MXML log (same sequences)//​ from the menu, and save and open the grouped log file.
