<div dir="ltr"><span style="color:rgb(0,0,0);font-family:Helvetica;font-size:12px">I've imported a cnt file that contains TTL trigger events. I defined a prestim time of 1 second and poststim time of 0.5 seconds. However, when I checked the cfg.trl matrix the offset shows "-5000". Can someone explain why?</span><div><br>
