Hi,<br>
<br>
The goal is to create Epochs with a baseline correction.<br>
Assuming event with id=8 indicates the start of a stimulus with a 40sec duration.<br>
The 5 seconds prior to that event (id=8) are considered as the baseline.<br>
<br>
I would like to know if I understand the epochs-initialization correctly.<br>
<br>
My parameters for the Epochs constructor are as follows:<br>
?tmin = -5<br>
?tmax = 40<br>
?baseline = (-5, 0)<br>
<br>
Or is it safer/better to set baseline to (None, 0) ?<br>
<br>
Conceptually:<br>
<br>
|-----------------------------<wbr>-----------> time<br>
|<- 5s ->|<- ? 40 sec ->|<br>
? ? ? ?8<br>
<br>
<br>
Kind Regards,<br>
Gertjan<br>

Hi,<br>
<br>
They should be the same but I would use (None, 0) because it would work<br>
even if you change tmin. Otherwise, no difference.<br>
