Thanks for showing me these solutions! After order the itemset , the second step is trasform the input file adding the cid as a dimension before sequence. So my input file will become like this 1 -3 5 20 -1 3 7 -1 -2 2 -3 16 -1 1 -1 -2 3 -3 3 4 8 -1 7 -1 -2 I will continue to work on it starting from your help!
