t-CWT for P300 feature extraction

Post by sandra2014 » 05 Oct 2014, 23:39

Hi, everyone .
Is there anyone know t-CWT ,a kind of method for feature extraction from ERPs. Recently ,I am learning about it , but I met some problems.
1. How to do the data preprocessing for t-CWT ?
2. If there is 180 trials (fifteen 12-trial blocks), that is, 30 trials belong to target group ,150 trials belong to non-target group, is that the case ?
Or after averaged, 2 for target group ,10 for non-target group?
Which one is correct ?
I am using matlab to do this experiment . And this is the reference.
ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=1300802
Anyone can help me ?


Thanks,
Sandra.
