<br>
you can either use the function "min" or "max" to find the minima and maxima in your data, or you can use the "peakdetect2"-function that can be found in the "private" folder of field trip.<br>
Another function, that is quite similar to the field trip-function is the "findpeaks"-function, in which you can even set parameters how exactly you want to define your peaks.<br>
Fo the latency: all the above functions can give you the index (i.e. sample point) of your peak, if you then compare this to your time-vector, you can get the latency until the maximum.<br>
<br>
Good Luck,<br>
