im designing a visual experiment with multiple loops. When I run the experiment it crashes after 1st loop. Error message: wrong syntax. It works well when I check off the box Is trial in each loop, but then I can’t get my trials data. I’m new at psychopy. Has anyone experienced something similar?
“Syntax error” simply means “the computer doesn’t understand what it was told to do”. Please give us the actual entire error message.
I’m hopeless at coding. That’s why I only use Psychopy Builder. But none of the experiments I designed are fully successful so far. On the 1st one, in order to get a set of loops running (matching pictures and sentences) I had to change data output so my data files are somehow unreadable. When I hit the button “Is trials” on the loop window, which would give me a neater datasheet, loops simply fail after some trials, giving me this message:

SyntaxError: invalid syntax
My second experiment seems even harder to fix. I set a sound capture routine which simply freezes my machine after a number of trials. No escape key can make it run again! I’m using blocks and time limit to minimize memory burden but so far no good has come. I have no message error available for this one because ever time I run this file, I have to reset my computer!

Has anyone got any idea of what those problems might be related to?
