Mac OS X 10.9.2 - Psychopy 1.80.01 - can't find image file trying to run program.

5.9685 ERROR Couldn't find image file '"/Users/Finn/Documents/Psychopy/self made/1.bmp"'; check path?

I'm using the builder view and I used a csv file to indicate the paths of images. When I don't use the csv file  and only type one path in the image stimulus dialog box，the image can be displayed properly. But when I list all paths in a csv file and form a loop of trails, I get the error message above. Note that every single path I typed into the csv file is validate.

I wonder that is the cause of this ?

Hi,
    I have no idea what might be going on, but a simple thing to double-check would be the space in your folder name.  I don't believe that spaces in pathnames are a problem for PsychoPy, but I have had problems with spaces in other programming environments, and it's a quick thing to test to see if it's the problem.  Why not try replacing the space with an underscore (so "self_made" instead of "self made") and see if things work.
    Good luck,
    Mark

Also, the last line in the error looks strange:

/Users/Finn/Documents/Psychopy/self made/"/Users/Finn/Documents/Psychopy/self made/1.bmp"

Did you somehow enter it twice somewhere?

Best,

Jonas

Ah, yes, you've got quotes in your filenames. Get rid of the quotes when you define the paths to your images

Also, it's a really good idea to give the path to your images in a *relative* way. i.e. specify the path relative to the experiment file, not the entire path. If you move your experiment to a new computer (or folder) all your paths will have to be changed.

Create a file structure like

    /Users/Finn/psychopy/self_made/
        selfmade.psyexp
        stims/
            face1.bmp
            face2.bmp

and then your image paths are just: stims/face1.bmp
It's much neater this way

Thank you so much. It turned out to be a problem with my csv file editor - "RuneCSV". Don't but this app.

And the suggestion you gave is really useful. Relative path makes it easy to share the experiment file.
