The problem is, that sometimes, 1 or 2 pictures just disappear from the screen after a few flickers.&nbsp;<br/>In raw data are registered all the pictures until the end, without showing that 1 or 2 are missing at some point.<br/><br/>i can`t find why this is happeningSun, 03 Apr 2016 15:26:24 GMTemiliahttps://forums.millisecond.com/Topic18758.aspxThanks!!! it works!!!&nbsp;<br/><br/>yeyyy :D<br/><br/>You`ve been of great help, thank you so much!!<br/><br/>Emilia<br/><br/><br/>Sun, 03 Apr 2016 15:26:24 GMTemiliahttps://forums.millisecond.com/Topic18755.aspxYou should be able to avoid that issue by forcing an explicit reset of the &lt;trial&gt;'s stimulus presentation sequence /ontrialbegin:<br/><br/>&lt;trial mytrial&gt;<br/>/ontrialbegin = [trial.mytrial.resetstimulusframes();]<br/>...<br/>&lt;/trial&gt;<br/><br/><br/>Sun, 03 Apr 2016 12:12:19 GMTDavehttps://forums.millisecond.com/Topic18752.aspxactually, i discovered the problem.<br/>is the beginresponstime (i don`t know why), but the problem is that when i delete it, the task doesn`t end when i press a valid key (even if it`s defined in the trial and in the defaults). the task keep going until the end. it doesn`t work even if set responseinterrupt = immediate<br/>if i let the beginresponstime, i can end the task when i press a valid key, but one of my images disappear<br/>any ideas?Sat, 02 Apr 2016 11:46:19 GMTemilia
