[Eeglablist] Realigning trials

Dear all,

We have a somatosensory paradigm where we cannot measure exactly when the 
subject starts feeling the stimulus. We do have triggers but there may be 
varying delays of tens to hundreds ms. Nevertheless, it's possible to get 
a kind of SEP. But I suspect it would look better if I found a way to 
realign the trials. I heard about Woody filter but maybe it would be 
better to try to align all the trials to the first or to use some kind of 
template.

I have some ideas about how this can be implemented but if anyone already 
has a working Matlab code for something like this (including Woody filter) 
it'd save me a lot of time and efforts. Suggestions and ideas will also be 
appreciated.

Thanks in advance,

Vladimir Litvak
