gabor patches in a code (v 4.0.4/5)

labovich

Hi everyone

I'm trying to create an enumeration task with equal luminance for all conditions and for that I want to use Gabor elements. I used Sigmund AI to write the code, but whatever I'm doing, it always sends errors about wrong use of colors. Every time Sigmund corrects it, I'm getting the same error, so I'm in this terrible loop.

enumeration.osexp

Is it a bug? Is it me? I'll appreciate any insight...

Best,

Tali

Hi @labovich,

I couldn't recreate your error with colour unfortunately. I got some errors about your canvas and keyboard items instead. Here's a corrected version that goes through your loop without any issue, but with the values you set in the script, the patches show up in the right corner of the screen, which I'm pretty sure isn't what you had in mind.

enumeration_v2.osexp

Can you tell me what the gabor patches should look like? Do you still get the error about colours with this version? If yes, could you send it to me?

Hi @cvanbuck

Thank you so much for the code!

I tried to run it (current version, windows 10), and right after the welcome slide got this error message:

Hi @labovich,

I see; have you tried putting 'white' (between quotes) instead of #ffffff already? (for the col1 parameter)

Claire

labovich

yes...

Weird... Both work for me... Maybe try uninstalling Opensesame completely, and reinstalling it with the installer package if this hasn't been done before? Are you up-to-date with your Python version too?

labovich

Thanks @cvanbuck ! re-installing actually worked!

cvanbuck

No worries, it might just have been some corrupted files or whatever, glad it works now! :)
