OS: Win10 PsychoPy version : 2021.1.2 **Standard Standalone? : y What are you trying to achieve?: I’m trying to set the image stimuli condition of different levels(A,B,C) and also different types(1,2). [Q0308_1] What I’d like to do is to present 6 stimuli of these combination (1,A), (1,B), (1,…

The easiest way to do this is to have 7 rows in your spreadsheet instead of 13 with Path1 and Path2 containing the two image options. Then in your experiment you could add a code component with the following in Begin Routine if random()>.5: Path=Path1 thisExp.addData('Path',1) else: …

Thanks for your comment…! However, it’s still a bit confusing. Is this what you mean by having 7 rows with Path1 and Path2? [Q0308_22] What I’d like to achieve is to show 6 combinations of images [ (Type = 1, Level = A), (1,B), (1,C), (2,A), (2,B), (2,C) ] in a random order. So, for every T…

That wasn’t the spreadsheet I was imagining. stimuli/1.PNG and stimuli/2.PNG should be in the same row because you want only one of the two of them to be shown. You still need a Type column.

Oh I see…! I changed the spreadsheet like this below, but then how can I set the path of image ? [Q0309_1] When there’s only one path, I could set up the image path like ‘$Path’. In this case, I have two path columns and how should I assign the image path that corresponds to the random selection…

Thank you so much…! It worked perfectly !! I really appreciate your time and efforts. Thank you again. Best wishes,

[image] wakecarter: if random()>.5: Path=Path1 thisExp.addData('Path',1) else: Path=Path2 thisExp.addData('Path',2) Hello, thank you for the helpful message. What if you have more than 2 paths how would you change the code? in my case, 6 for images: (image1 image2, ima…

You could have columnChoice = [1,2,3,4,5,6] shuffle(columnChoice) thisExp.addData('imageN',columnChoice[0]) if columnChoice == 1: thisImage = image1 elif columnChoice == 2: thisImage = image2 elif columnChoice == 3: thisImage = image3 elif columnChoice == 4: thisImage = image4 …

Thank you! Begin Exp: image_list = [ ] word_list = [ ] This gives error : thisImage = image_list.append(image1, image2, image3, image4, image5, image6) thisWord = word_list.append (word1, word2, word3, word4, word5, word6) How am I going to define each column? what is the image path f…

[image] wakecarter: then repeat for the words Thank you! Begin Exp: image_list = [ ] word_list = [ ] This gives error : thisImage = image_list.append(image1, image2, image3, image4, image5, image6) thisWord = word_list.append (word1, word2, word3, word4, word5, word6) How am I going t…

Why are you appending? I’m assuming that image1-image6 are names of your columns. That could include the path or you could add that in the code thisImage = 'images/'+image6+’.jpg’
