[Traminer-users] Occurence of sequences and time

[Zéphyrin Soh]

Hi TraMineR users,
I look at TraMineR and I wonder if someone can help me to deal with this 
two problems:

1. Subsequence/substring mining: I can find if a sequence contains a 
subsequence/substring. But I would like to know the number of occurence 
of subsequence/substring in a sequence.
I am interesting in the substring and not subsequence. As I know, 
subsequence also consider non consecutive states, but I want to consider 
only consecutive states.
For example, in the sequence A-B-A-C-B-A-C-A-B-A, I would like to have 3 
as the number of B-A in the sequence.

2. Time: TraMineR consider the time as the time when the event occurs or 
when the state is reaches. Am I wrong?
I would like to consider the time spent (duration) in a state. AAs the 
duration (in sec. for example) can be a "double"  (e.g., 4.73), is there 
any way to mine sequences with states/events duration?

Thanks in advance for your help.
Zéphyrin.
