[solved] Set the duration of a sketchpad according to the length of the current sequence
I am actually making an OpenSesame version of the ANT (original by Fan et al., 2002).
I have two main problems.
Each trial must last 4150ms. To get this length, i have: a 1st sketchpad (random duration between 400 and 1600ms) ; 1 sampler + 2 sketchpads (total = 650 ms) ; a keyboard response ; and a last sketchpad.
So, i have to find a way to set the last sketchpad in order to make it last :
4150ms - 650ms - 1st sketchpad duration - response time.
I have tried Sebastiaan's solution from http://forum.cogsci.nl/discussion/505#Item_8 but it looks like i still don't have a "calibrated" time for each trials. When i try to read the logs, the length of each trial is around 5000ms but never the same time.
I want to get the exact time (UTC) at the beginning of each trial in the logger. But i don't know how to do it.
Did someone have the same issue?
I hope i have been clear, ask me if you need more informations.
Thank you in advance.
