I got a conversion problem. Please see the attached photo and excel file for your reference!
I added placement to stimuli list(excel file) and it contains (-0.4, 0) and (0.4, 0) to change position two image stimuli. But they can’t be converted as a number.
How can i fix this problem?
If you add comments, they would be really helpful!
Thank you for all your help.
Columns for the X and Y coordinates were generated. i attached the stimuli list.
But error was still in my experiment… Could you review my code?
