Press this icon to compile your Builder file and open it in Coder. [image] However, I would not recommend editing a Builder experiment in Coder. [image] Wakefield's Daily Tips Blog Builder isn’t Coder I strongly discourage the use of PsychoPy Coder for the …

Thank you so much for your help! If you don’t recommend using Coder for experiments developed using Builder, would you be able to let me know how I can edit the duration of each of my experiment blocks in builder view (or point me in the direction of a helpful thread/instruction guide). I have had t…

[image] kumarvar: the duration of each of my experiment blocks Please clarify. Do you mean routine duration or exiting a loop early? What sort of code were you thinking about adding?

The experiment I am trying to edit has 4 experimental blocks (e.g. A - B - C - D) and this repeats 4 times. Each block (e.g. A) has a duration of 10 minutes. I wanted to try both of the following: Changing the experiment so that each block runs for 5 minutes instead of 10 minutes. Making it so the…

If it currently runs for 10 minutes, that’s probably in a code component somewhere. I would start a clock in Begin Experiment (myClock = core.Clock()) then reset it before the loop starts in End Routine (myClock.reset()) and then check it at the end of each loop (e.g. End Routine in feedback). if m…

Thank you! That makes sense and I will look out for this in the Python code. I did have a follow up question. I noticed that when I click the button you mentioned to get the ‘Coder’ version of the experiment, that it creates a separate python file of the experiment. If I were to make changes to this…

[image] kumarvar: If I were to make changes to this file, are they also applied to the .psypexp file that already exists? No, which is why I discourage editing the Python file directly. When you run a Builder experiment the first step is that it generates a Python file (lastrun.py) and then …

Got it, thanks for the clarification. I have a follow up question. If I did want to change the time it runs from (e.g. from 10 minutes to 5 minutes) , then I would only be able to edit this in the builder version of the code? Would you be able to let me know how to do this or if there’s a resource I…

Try searching for 600 via Edit / Find in Experiment to locate the current code. There should either be a variable set to 600 or a component duration or a comparison with t or a clock in Each Frame.

Hi again, thanks very much for your help! I was able to find a piece of code that had 600 and I modified it for my testing. I’ve included it below for context: if ((loopTimer.getTime() > 60)) { currentLoop.finished = true; } I also made changes to the workflow (removed a particular block) and s…
