Hi! I am using a Real estate database to find relations between price and characteristics of the house. I want to create association rules for the top 50 itemsets, I tried using operator "FP-Growth" and I succesfully create the table of the most frequent itemsets with a column of Support. The problems is when I tried to aggregate the column of Confidence and Lift using the operator "Create Association Rules". It doesn't use the first table, instead, it use all the database again, adding to the final table more than 50 itemsets..

Please! I would appreciate your help :)   (sorry for grammar mistakes, English is not my native language)

    There are two conflicting parameters in FP-Growth - one is min support/frequency and the other is min number of datasets. The latter will overwrite the first. So if you want to be strict in using (and passing further to Create Association Rules) only those items which have sufficient level of support, click off the "min number of datasets" option.
