How do I find the most frequent sub sets for this data?

leomonneretleomonneret Member Posts: 3 Learner I
Hello everyone!
I have tried to apply many different operators to this data set so it runs through FP-Growth but no matter what I do, FP-Growth does not display any subsets at all. 
The best I can get is "true" and "false" results. 
I think maybe I could be a problem with the dataset, so I tried using aggregate concatenation to have it as a list but it still does not seem to produce the right results. 

I will join the data set to my question if someone could help me it would be really great!

Thanks a lot rapidminer community!

    I think you only needed a bit of preprocessing.

    Thanks a lot, I am trying to repeat the same process in RapidMiner and I am struggling a bit but hopefully I'll manage. Thanks again for the help!
