Running experiments with batch file

Hello,

I'm designing an experiment with a lot of canvases (with inline script, for animation), and therefore the experiment is too heavy to be in only one osexp file (I get "out of memory" error).

To solve this problem, I divided the experiment into defferent parts while each part is in a different osexp flie. I want the experiment to still be continuing, without breaking after every part. So I though to use batch file with opensesamerun commands to run all the parts sequentially, but my problem is that I need all the "heavy" sections= all the canvases preparetion, to be before the experment begins.

Is there a command with opensesamerun for specific osexp file just to do it's prepare parts, and only after it to run the experiment? so I could prepare all the different experiment's parts at the top of the batch file and after it to use '.run' command without waiting for every part to be prepared?

Sorry if my explanation (and my spelling) is a bit of a mess :|

Thanks!

  • Hi Bar,

    There is no easy way to change how the prepare and run phases are handled. The logic is always that the prepare phases of all items in a sequence (or coroutines) are called first, and then all the run phases. You could write a script that explicitly calls the prepare() and run() functions of all items, but this doesn't seem like a great idea to me.

    By default, the automatic garbage collector is disabled in OpenSesame. This means that Python doesn't automatically free up memory while an inline_script is running, but only does so at the start of each sequence. You could see if re-enabling automatic garbage collection (in the General Properties tab of the experiment) solves the memory issue?

    Cheers!

    There's much bigger issues in the world, I know. But I first have to take care of the world I know.
