Images not found in file pool

LBell4291

Hello All

I really hope someone can help me! I am in my final month of uni and we have to make a psychological experiment on OpenSesame. We have to use a slightly older version - and we have been told not to update. The version we are using is 3.0 and Python 2.7.

I have figured out how to do a lot of things on OpenSesame but no matter what I do it keeps saying my image can't be found.

The idea of my experiment is to look as systemic Racism. So the participants will be shown a video of several news and media clips and then be shown a series of images. The time will be logged and the basic idea is that people will click on images of certain races quicker than other due to how things are presented in the news.

This experiment isn't looking to 'out' people - but more looking to show that the news and media misrepresents races differently without actually being aware.

The images will show people with or without weapons. To see if 'weapons' are seen quicker in images when a certain race is in the picture or not.

I have followed the manuals and when I 'edit the script' so change it so a different image is shown at each loop, I get the same message to say 'image33' cant be found.

If anyone can help it would be greatly appreciated. I don't want to fail my uni work and I am starting to really panic. I have contacted my tutor and been told that they only have the same instructions that I have and no help has been offered.

Thank you so much in advance and sorry for the massive comment!

Hi @LBell4291 ,

Based on your description I suspect that you haven't specified the extension for the filename of the image. Probably, your images aren't called image33 etc., but image33.jpg or image33.png . If that's indeed the issue, then adding the file extension (e.g. .jpg ) to the file keyword in the script will solve the problem. However, to tell for sure you'd have to attach the experiment file here and provide a more detailed error message!

PS. I edited the title of the discussion. There's no need to use capital letters to indicate that you need help--needing help is implied when you post a question on a support forum.

Hi Sebastiaan,

I do add .jpg or .png to the script but the error keeps occurring, I can take a screenshot if that helps?

Thank you - like explained I am getting quite worried. I find it quite strange that others can change the title as you could really change it to anything then! but thank you.

Hi @LBell4291 ,

A screenshot would be helpful, but then it needs to actually show the relevant parts of the code, so at least the script of the sketchpad and also the contents of the file pool. Attaching the experiment itself would be better.

Yes, in theory I could do that. But then again, I did make the forum (and OpenSesame), which gives me some special privileges!
