Dear Fran,
I see. This feature would be possible but it is maybe not so easy to add. Something tricky about this is that a pattern may appear multiple times in a same sequence. For example, the pattern (A,
(A) appears at least 5 times in the sequence (A,B,C)(A,
,(A,B,D)(A,C). Thus, if I understand well, you would like that the program indicate each occurrence of the pattern in that sequence?
For example, it could be said that
the first occurrence of (A,
(A) is 1st itemset, 2nd itemset
the second occurrence of (A,
(A) is in 1st itemset, 3rd itemset
....
Because each algorithm is different, I think that to add this feature, it would require to choose one algorithm to modify it for that. Or another way that would be less efficient, would be to do a post-processing step to highlights the occurrences of each patterns in each sequence where it appears. This would maybe be easier to do. Which algorithm are you using?
Best,
PHilippe
