<div dir="ltr">Dear Lei,<div><br></div><div>I think that you are asking that you want to run the steps again, with prestim =0.5 but with rejecting the same 10 trials that you already have decided to reject? If so, the numbers of rejected trials should be inside data_reject.cfg (or possibly data_reject.cfg.previous). But note that by including more prestim time, you might also find a need to reject more trials if there is an artifact in the new included prestim time-points. If you use ft_redefinetrial, I think you only would shift where the time 0.0 is, but not add more data to each trial, so it depends which you want to do.</div>

<div style="direction:ltr;font-size:12pt;font-family:Tahoma">Dear Fieldtrippers,<br>
<br>
I am new one to use the fieldtrip, and have a question about the rejected trials.<br>
To be simply, let we say:<br>
1) the original data is data_org, one singal trial in 32 channel, with 2 different trigger codes and 100 trials per trigger.<br>
2) I process the data to the data_stimulus, incuding 200 trials. Each trial has prestim = 0.1,<br>
poststim = 1;<br>
3) I do ft_rejectvisual to reject 10 trials, 5 for each trigger. Then I get data_reject, including 190 trials.<br>
<br>
Here is the problem. I found the prestim is too short, I want to increase the prestim time to 0.5. How can I get the numbers of rejected 10 trials to do ft_redefinetrial?
<br>
<br>
Thanks,<br>
