Hello,
My lab PI created this code from Matlab and wants me to apply it to an image. The experiment crashes when run and I put the code down below.
Error:
3.7567 WARNING We strongly recommend you activate the PTB sound engine in PsychoPy prefs as the preferred audio engine. Its timing is vastly superior. Your prefs are currently set to use [‘sounddevice’, ‘PTB’, ‘pyo’, ‘pygame’] (in that order).

This screenshot shows the coordinates for the image in Spyder
I’m not really sure what to do to fix this or how the code is even finding Master H and V without a file…
